Section 4 Flashcards
1
Q
_______. _______ Is an incredibly valuable component of the design process, and it’s something that will likely come up more than once in various stages of the process?
A
Evaluative research
2
Q
What will you want to run as you refined and iterate your designs?
A
Multiple usability test
3
Q
Utility?
A
The features and functionality needed to complete important task
4
Q
Usability?
A
How easy your project features are to use, as well as whether they bring satisfaction
5
Q
Useful= what?
A
Useful= usability + utility. For something to be useful, it must address the functional and emotional requirements expressed by your target audience during research
6
Q
The only way to find out if they design is useful for others is to?
A
Is to test it with valid evaluative of research methods
7
Q
In addition to designing useful and usable products and services, they must also be?
A
They must also be desirable, accessible, credible, and findable to deliver real value to real people. Sound familiar?
8
Q
With UX design what is the research method which is similar to the scientific method?
A
In design, we start by asking questions and identifying a problem, then we create a hypothesis often in the form of a prototype, and, finally, we conduct various iterations of evaluate of testing to analyze the usefulness of the thing we’ve designed.
9
Q
Informed consent?
A
Informed consent is the process of helping research participants make an educated decision as to whether they want to take part in your research. Informed consent describes the nature, intent, and details of your study to participants allowing them to make a conscious decision on whether or not they want to participate
10
Q
In addition to informed consent, you’re also want to tell your participant what?
A
Whether they will be recorded and how that recording will be used
11
Q
When conducting a usability test, make sure your participants understand what?
A
Understand that you are Not testing them or their capabilities, but rather your design.
12
Q
Assure the participants that there is a what?
A
Assure them that there is no way for them to sell, and that if they can’t complete a task, it’s simply the fault of the designer
13
Q
What is the main point of performing usability test?
A
Highlighting and catching your own mistakes as a designer
14
Q
Ideally, when outlining your research and recruiting participants, you want to find people who are what?
A
Who are different from you. In fact, testing edge cases of your design with participants who vary greatly from yourself/your typical target audience often creates incredibly insightful results, especially if there’s a known or unknown subset of users who might end up engaging with your design beyond your primary persona
15
Q
While it is most important to test with your primary persona, ensuring that you run some usability test with who?
A
With those dissimilar to you or your persona is a good way to ensure your designs are useful to as broad and audience as possible. This will also help you avoid general research issues such as sampling bias, which causes errors in Results due to a non-random selection of test participants
16
Q
Third party online services?
A
Third-party online services help recruit participants using a specific demographic information such as age, gender, and location. Test are often online and unmoderated, and results are delivered as a report or video. Usability testing, users zoom, and usability hub or a few
17
Q
Amazons mechanical Turk?
A
Amazons mechanical Turk is useful if you need to recruit a high volume of participants at a low cost. It allows you to set up a test and pay anonymous people a small amount to complete quick tasks
18
Q
Classified advertisements?
A
Search is Craig list or local classifieds might be a good place to find local participants. Panel agencies such as research now have large databases of potential participants available for unmoderated test. Cost range between $15 and $55 per response
19
Q
When contacting potential participants you don’t know, it’s extra critical that you do what?
A
It’s extra critical that you introduce yourself and the project properly and explain the expectations and incentos for the test participant the circumstances of the project may vary, but in general, there are a few types of common templates/messages researchers used to contact potential participants. usability.gov is a great place to look for recruitment, confirmation, and reminder email templates
20
Q
List five tips for writing effective templates/messages?
A
Keep your messages brief. Format your message for easy reading. Use simple language. Clearly explain the expectations of the study. Highlight the incentives. Make the Recipients desired action clear
21
Q
What do we conduct interviews and card sorts for?
A
To explore user needs and decided on the features and functionality needed to accomplish specific goals
22
Q
What do the features in a prototype provide?
A
These features provide the utility necessary for something to be useful. Assuming you have successfully determined and built the features you need through your generative research methods, we can now isolate the other important variable in the equation/usability
23
Q
Usability?
A
His ability refers to the ease with which people can use your product or experience. In order to test a products use ability, we conduct useability test
24
Q
Usability?
A
Usability refers to the ease with which people can use your product or experience. In order to test a products usability, we can ducks usability test.
25
Usability testing?
Usability testing refers to a collection of methods that design researchers use to measure and improve usability. Usability testing comes in all shapes and sizes.
26
List three things that all methods have in common?
Test participants that represent a subset of the audience you are designing for. A realistic set a task for participants to attempt. Users actions and thoughts recorded as data.
27
Utility?
Whether it provides the features you need
28
Usability?
How easy and pleasant these features are to use
29
Useful?
Usability + Utility
30
List two types of generative research methods?
Interviews. Card sorts.
31
Give the reason for conducting interviews and card sorts?
32
Now that you have a working hypothesis and something to evaluate your prototype, let’s take a look at the other half of the research spectrum which is what?
Evaluate of research methods
33
Quantitative data, for example, is incredibly useful win?
It is incredibly useful in determining the magnitude and degree of behaviors and attitudes, but it does not always give us insight into the why or how to fix the problem. Likewise there are stages when researching what people say is more important than researching what people do and vice versa. Everything depends on the situation at hand.
34
Context of use?
Is the third dimension of the graph, referring to the context in which we gather information from people. Context abuse can be incredibly important depending on the nature of the problem you are trying to solve. If you are designing technology to help engineers install satellites on top of skyscrapers, for example, the context of use might be critical as it’s a highly unique circumstance. In such cases, it might be useful to observe natural used to better understand the environment.
35
Eye tracking?
Org gazing tracking, is the process of measuring either the point of gays, where one is looking or the motion of an eye relative to the head. The image above shows how a user typically scans a website. And I tracker is a device for measuring I positions and I’m movement and can be configured to measure precisely where participants look as they perform task or interac naturally with websites, applications, physical products, or environments.
36
Pros of eye tracking?
Eye tracking can be useful in determining the location of specific events. It is possible to use remote versions to track mouse movement with the hypothesis that mouse movement closely correlates to I movement, but it can be difficult to glean accurate insights from large groups.
37
Cons of a tracking?
Eye tracking Equipment can be incredibly complex and difficult to calibrate. It is possible to use remote versions to track mass movement with the hypothesis that mouse movement closely correlates to IM movement, but it can be difficult to Glenn Acura insights from a large group
38
When to use eye tracking?
Sophisticated organizations with adequate funding and expertise can employ eye Tracking as additional data to inform their design decisions. Heat maps the aggregate a movement or mouse movement can provide a useful snapshot of activity to help inform design.
39
Ethnographic field studies?
Involve observing participants in their natural environment. You might notice a sound similar to gorilla testing, which we discussed in the previous exercise, however, gorilla testing tends to focus on the functionality of the system in question, well ethnographic field studies tend to focus on the test participants personal attitudes, behaviors, and environments
40
Pros of ethnographic and field studies?
The studies can yield incredible rich information about not only behavior and attitude with a product or service, but a participants general habits and environment, as well. Given the time and funding, it can yield valuable information about your customers that you would miss out on by focusing simply on the product and it’s usability
41
Cons of ethnographic field studies?
Test can be expensive from both a time and a financial standpoint
42
When to use ethnographic field studies?
Given sufficient time in funding, he studies can be a great step towards designing more accurately for highly specific context and use cases.
43
A/B testing?
Also known as live testing, Bucket testing, or split testing, is a method of scientifically testing different designs on a site by randomly assigning groups of users to interact with each of the different designs and measuring the affect of these assignments on user behavior. You could test, for example, multiple versions of a sign-up process for your site, multiple email layouts for your newsletter, or the success of text versus video in an online tutorial. When more than two choices are necessary, researchers my also use a similar process called Multivariate testing
44
Pros of a/B testing?
Quantitative results provide definitive direction so long is the test set up and results analysis are sound
45
Cons of a/B testing?
There must be significant traffic and usage of your product or service in order to garner useful data, and it can take a long time to gather enough data to reach statistically powered results. This means that you need a larger number of participants to be able to generate plausible test results. Expertise in data science is also required to make an accurate decision as to statistical significance and power
46
L When to use a/B testing?
For products or services with significant traffic in usage that also have teams with expertise in setting up a/B test and Downloading results
47
Five second tests?
Are used to determine whether a particular webpage or app screen does a good job of getting its core message across. For example, if you have a webpage of which the main purpose is to have visitors sign up for a newsletter, you could use a five second test to determine whether the users recognize that this page was asking them to sign up for a newsletter
48
Another name for five second test?
Memory test
49
Pros of five second test?
A five second test is quick and easy to run. You just need a representation of the website or app screen you’d like to test, which can be anything from a paper prototype to a high fidelity market, and a set of questions you would like to ask users about what they remember from looking at the screen. Users are then Shown the screen for five seconds and asked to prepare a set of questions before the screen is covered or switched to a different one
50
Cons of five second test?
Five second test are not well suited for screens that have multiple functions is they will be difficult for users to assess in such a short space of time, and different users are likely to focus on different functions features, leading to inconclusive results
51
When to use five second test?
Five second test our best Suited to testing screens that have a single primary purpose such as signing up for a service or downloading a piece of software
52
Usability testing refers to what?
Refers to a collection of methods that design researchers use to measure and improve usability. It’s a type of evaluate of research used to measure they use ability of your design by testing and interactive version of the design with users
53
What is usability testing?
It is a technique used by UX designers, design researchers, and interaction designers to evaluate the utility and use ability of a prototype or live product. Due to the flexible nature of usability testing, it is the most common method employed by UX designers, which is why we will be focusing on it for this course. As the name implies, usability testing involves testing the use ability of your product on a set of users. It is a great way to evaluate what people say and do when interacting directly with your product or service. Most often, users are given a specific set of task to complete, and efficiency, ease, and speed with which they can’t complete them are recorded. Keep in mind that it is not the participants themselves being tested but the effectiveness of the product or service you have designed
54
Why conduct a usability test?
And effective usability test reveals how a typical user would attempt to complete a task using your product. It can also grant insight into how to fix problems that may arise during the test. Researchers can observe where participants get confused or make wrong choices, take notes, and then implement steps to correct the issues. Usability testing doesn’t have to be expensive, and it can be a great way to quickly game insights that inform design decisions
55
A well structured and successfully executed usability test helps designers make better decisions by demonstrating what four items?
The ability of participants to complete task. How long it takes participants to complete task. Whether participants enjoy interacting with the product or service. Whether the product or prototype has any critical errors.
56
Conducting a usability test before rolling out a final product design will do what?
It saves time and money for a company and helps ensure the final product will be well received by it’s intented users. Rather than spin resources creating a final, polished product, designers can quickly iterate and course correct several times before investing in a final design to hand off to developers
57
Who is involved when conducting a usability test?
Ideally, you would have at least two researchers involved, one to conduct the usability test and another to take notes and record results
58
Where do you usability test take place?
Test environments vary according To the scalp and nature of your project. There is a common misconception that usability testing requires a formal use ability Lab and that recruiting participants is expensive. In fact, there are a variety of ways to conduct an effective usability test depending on the nature and constraints of the project. Ultimately, the test environment and setting will depend on the goals of your study, as well as the time and geographical constraints on the researcher and test participants
59
Try asking yourself the following questions about your usability test project for a better idea of what a proper usability test will require what two items?
Does the usability test require a moderator to facilitate the test? Will the test take place remotely or in person?
60
Gorilla testing?
??????
61
What is another name for gorilla testing?
It involves Intercepting people in their natural environment and asking them to complete a quick test. This is especially effective if you have access to your target audience and the nature of your study doesn’t require sensitive information from participants. It is all right to ask for example, can you add this T-shirt to your cart? As the primary subject is the T-shirt and the capability of the system. In contrast, it might not be good to walk up to somebody and ask, when was the last time you have taken prescription medication? This is about the participants personal situation that should be handled with informed consent and additional explanation, making it A difficult subject to breach with a gorilla test
62
Field studies?
It involves observing participants in their natural environment, where they would be most likely to engage with your product or service. Well gorilla testing tends to focus on the functionality of the system in question, field studies tend to focus on the test participants personal attitudes, behaviors, and environments
63
Usability test labs?
Require an investment in time, space, and equipment, but can be a great way to facilitate test then allow for observations from other researchers and team members. Many companies and academic institutions have built usability labs that allow researchers to bring participants in for interviews, then test and record participants in a seemingly natural yet highly sophisticated setting. Usability test labs often have a variety of devices such as audio and recording equipment and sometimes even a two-way mirror to allow stakeholders and researchers to observe without Distracting the participant
64
When do researchers conducted usability test?
This is probably the hardest question for designers to answer. Not only does it depend largely on the project itself, it also requires experience on the part of the designer, enough projects under their belt that they have developed a feeling for when and what to test. Usability test RN effective way of obtaining feedback and should be conducted throughout the design process. But it’s ultimately up to the design researchers to determine the best time and factors to test and to achieve the best results. Every project is different. Good designers know how to conduct usability test. Great designers also know when to test. At this point, focus on how to test. Once you are working as a designer in the field, you will be able to observe when usability test you the best results for each particular project
65
How much do you usability test cost?
The short answer is it depends, just like so much when it comes to usability test. Cost can vary wildly depending on the complexity, budget, and depth of research necessary to make good design decisions. Where you are conducting your research can also play a factor in the cost, so it is difficult to give an exact number. In the US, rates can range from free all the way up to hundreds of dollars per response if utilizing third parties or if the participant is of a highly specific target audience
66
List three factors that can influence the cost of your research?
Usability test method. Number of participants. Time allowed.
67
Usability test method?
Exact methods will be covered in the next section
68
Number of participants?
Often times you only need five participants to catch most usability issues and inform design decisions
69
Time allocated to usability test?
Keep in mind that for every hour of testing, you will probably need two hours afterwards to download results and communicate feelings to the rest of your team. If possible, it is best to run multiple short test instead of Long, time consuming test. Time is money, as they say
70
How to conduct usability test?
Daily, usability test are conducted with test participants from a specific target audience. Participants are usually asked to complete task using the product or prototype wow the researchers watch, listen, and take notes. It is important to have a test plan and test strip to make sure the test are consistent. We will be working on creating these over the next couple of exercises. The primary goal of your test is to pinpoint usability problems through behavioral observation and determine participants satisfaction with the product or prototype
71
You may remember from the intro to UX design course that there are three basic types of usability test methods researchers used to gather feedback from real people, what are they?
Moderated in person. Moderated remote. Unmoderated remote.
72
Moderated in person test?
Require a researcher poor facilitator colocated with the participants often in a lab, though locations can bury. The researcher and/or observer facilitates the test via a script, typically creating a more controlled test with more specific results. This is because a moderator is able to ask follow-up questions and can observe body language in addition to verbal responses. There are, however, a few drawbacks to this method. First, this kind of testing tends to be more time-consuming as the moderator must be physically present, and second, that same physical presence can change the way certain participants respond, potentially skewing data
73
When to use moderated in person test?
Moderated in person test are especially useful during the early stages of prototyping. At this stage, the prototype is likely missing certain functionality, and users might require guidance to complete the desired task. Moderated test are particularly effective at digging deeper into the way behind a participants behavior, which can be crucial in guiding design decisions and feature priority at the beginning of the project. Alternatively, if you have a very mature and complex prototype, a moderator can help keep test participants on track, only testing the current area and task of interest. While recruiting participants can be time and cost intensive, researchers often manage to find local participants to volunteer their time for little or no cost, especially if interest already exists for the product or service.
74
Moderated remote test?
Are useful when the participant and facilitator are in different locations. Screen sharing software such as go to meeting, Skype, and slack, among others allow the facilitator to watch remotely as the participant attempts to complete specific task using their product website
75
When to use moderated remote test?
Moderated remote test are useful when participants and facilitators are geographically distant and can’t meet in person. It allows for participants to use their own technology in their own environment, which can sometimes yield more authentic results
76
Unmoderated remote test?
Don’t require the physical presence of a moderator and are, instead, conducted a synchronisically, online using a variety of specialized tools such as user testing, users zoom, or usability hub. The asynchronous nature of online test gives researchers more flexibility in recruiting participants and running test, allowing for a higher volume of responses. One drawback, however, is that researchers are not able to observe body language or ask follow-up questions. Gathering mountains of unmoderated data can be valuable so long as you have the time, resources, and knowledge to analyze the results and communicate them effectively to the rest of your team. Don’t pay for 1000 hours of recordings of your website, for example, if you do not have 1000 hours of time to devote to watching the videos and creating useful conclusions. If your time is limited, it might be better to aggregate results in the form of
77
When to use unmoderated remote test?
Moderated test are most useful when testing very specific task for a mature project or platform. Incrrased granulary and a higher volume of responses can be useful when evaluating a specific task or feature. Unmoderated test also mitigate geographical and scheduling differences between researchers and participants. Online tools can be expensive, so a certain level of funding will likely be required to conduct sophisticated and moderated task. What’s true about evaluate a test methods as a whole is true of the ways in which you can conduct usability test, moderated in person, moderated remotely, unmoderated remote, they each come with their own advantage and disadvantage is, and choosing one will depend on a variety of factors, including your budget, time, and testes purpose
78
Evaluate research provides an important what?
It is an important counterpoint To generative research
79
Wow the generator research you conducted towards the beginning of your project helped in what way?
It helped shape your persona, the problem you are addressing, and the features you will design, evaluate of research is your chance to test whether those features are usable with real people and update your design accordingly
80
There are many methods fall on the evaluate of research side of the spectrum, including what?
???????
81
The most common an important way to conduct evaluate of research, however his what?
Is via usability testing
82
Usability test or an easy way for real users to do what?
To interact with your prototype in for you to observe what they do and where they struggle. It is also fairly flexible and can be done in a number of ways, from moderated to unmoderated and even remote testing
83
What is a usability test plan?
A document that will help you clarify the various components of your usability test
84
List a few guidelines to consider I’m preparing for a usability test?
Experienced user researchers select in combine methods to suit their project and the questions they are trying to answer. Keep in their main focus on maintaining a clear vision of what they want to learn and how it will inform the team and direction of the project, then lay out clear goals and structure for the test via their test plan
85
Before beginning any test, it is important to create what?
A usability test plan
86
What is a usability test plan?
It is a document that outlines the scope, goals, and logistical details of your session in advance. Test plans can be highly detailed or short into the point depending on the research goals immaturity of the project
87
At the beginning of a project, it is a good idea to keep things short for what reason?
It is a good idea to keep things short, especially if you will be communicating with other stakeholders who may need to understand the main points quickly and efficiently. This will allow you to better allocate your time and perform any quick test while iterating on and improving your prototype. In a larger company or project, you will likely meet with several stakeholders to decide on the details of the test plan
88
List the 12 mean elements of a basic test plan?
Introduction. Background. Goals. Test objectives. Methodology. Participants. Schedule. Sessions. Equipment. Metrics. Scenarios/test task. Script.
89
Introduction?
Start by recording the date, time, and location. Include the names of all those involved in the test from designers to stakeholders. Give your test plan a title that indicates what you are studying and the type of test for example, triply moderated usability test, mobile navigation
90
Background?
What are you testing? Include the name of your app, persona, problem statement, and if applicable, the specific area you are testing e.g., navigation or check out flow. Keep it short, imagine you are providing context for a colleague or stakeholder unfamiliar with the project
91
Goals?
Outline a main goal or a limited set of goals in a sentence or a few bullet points. This is the overreaching result you would like to accomplish with your test. If it turns into a long essay, consider breaking it up into multiple test plans.
92
Test objectives?
What specific features are you studying? What primary questions do you want your usability test to answer about the specific features? This is where you will list the features and relevant associated questions in your test plan
93
Methodology?
What specific features are you studying? What primary questions do you want your usability test to answer about the specific features? This is where you will list the features and relevant associated questions in your test plan
94
Methodology?
What method will you use for your usability test? Moderated in person, moderated remote, or unmoderated?
95
Participants?
How many participants will you be testing? How did you or how will you be recruiting participants? Are there any special details or characteristics to note about the participants, and, if so, how these characteristics relate to the goals of the study?
96
Schedule?
Where in win will you meet your test participants contact them in advance to schedule a place in time. Make sure you have enough space for you and your participants, as well as access to the technology you will need to conduct your session. Include the date, time, and location of your test for planning purposes
97
Sessions?
This is where you will record the length and scope of your sessions. Session times are variable depending on the complexity of the project, usability test, and task. For the purpose of your project, shoot for 10 to 15 minute individual sessions with at least six participants from your target audience
98
Equipment?
What devices will you test? Are you using anything to record? If you are testing on your mobile device, for example, record that here. If you are planning to record video or audio during your test, what equipment will you need, and what programs will you use? You can add more detail to the section leader in the achievement, when you take a look at specific recording software
99
Metrics?
????
100
Scenarios/test task?
You will want to know what you will be asking your participants to do in advance to ensure you are collecting the same data from every one of your users. In the last exercise, we talked about the importance of zooming in on a limited number of critical features for a given usability test. In the next exercise, we will be discussing how to create task, referred to as a scenario in direct task, to test the features you have identified
101
Script?
A test strip is used to help facilitate the conversation during your usability test, we will discuss how to create a test strip in the next exercise. If Your test strip has not been written at the time of drafting your test plan, you can simply write TBD which means to be determined and link the script at a later point in time
102
How many people do you need to test?
At least six people
103
How long should these individual Test take?
10 to 15 minutes
104
What is the goal of the study?
It is to assess the learn ability for new users interacting with the travel application for the first time on mobile and desktop. We would like to observe and measure if users understand the project, its value, and how to complete basic initial functions such as logging in and searching for/navigating to a desire travel experience
105
Once we defined the overall goal of our research, zoom in an outline want?
Outline the specific test objectives, including the specific feature or testing EG, login screen, search bar, or navigation buttons etc.
106
Test objectives?
Test objectives are more specific then goals and highlight the particular features will be testing in order to achieve our test goal
107
For each teacher, make sure to pose what?
Make sure to pose a few research questions you would like to answer with your usability test. Try to highlight only the most important objectives, keeping the number ideally under five. It is nearly impossible to conduct effective research without concentrated focus on just a few specific goals. You may want to start with the features you identified as being particularly important in the previous exercise.
108
List for questions to consider when outlining your test objectives?
What are the specific goals of your research based on your internal audience, external customers, and current state of the project? What components of usability are important to your project at this stage, useful, usable, desirable, accessible, credible, findable? What specific questions will be answered by conducting this research? What hypothesis will be tested?
109
List to test objectives?
Measure how quickly participants are able to login, as well if there is any hesitation to providing personal information. Find out if participants can easily locate the Search function
110
Objectors measure how quickly participants are able to login, as well as if there is any hesitation to providing personal information, list the three research questions that go along with this?
How fast can people login? Do people seem anxious about providing personal information? Where are the most common errors users make when entering data?
111
Objectives find out if participants can easily locate the search function, list two questions that go along with this?
Can participants easily find the search? Do you the search results meet their expectations?
112
BRD?
Business requirement document
113
Why is this a good time to review your BRD for the project?
This is a good time to review the BRD or business requirements document for your project to ensure you are testing the features most critical to meeting the business objectives and function requirements laid out by the initial project team.
114
Questions you might ask to determine who the audience of your research is?
You will also want to determine the audience for your research. Your target audience will influence the goals in terms of the results you will want to deliver. Who are the stakeholders? Product managers? Marketing specialist? Engineers? Other designers? You need to have a clear understanding of who you are we searching for
115
It is entirely possible that the most important audience will turn out to be who?
Your self or other designers
116
Success criteria?
Success criteria simply define a measurable outcome or qualitative insight you can use to deem something successful or not. Your success criteria, problem statements, and user stories will help you narrow down your focus to only the most important features you need to test. Let’s go over a few ways to add success criteria to your hypothesis statements
117
What is the success criteria format?
We will know that the hypothesis to be true when we see this feedback/qualitative insight/quantitative measurement
118
An example of success criteria format?
We will know that our hypothesis stating that the download button and the navigation bar for a guide would be effective is true when 90% of test participants can complete the task, download a guide for off-line use
119
It is important to clarify a number of things about your participants?
How many there will be, who they are in terms of any special characteristics necessary to run the test, and how you plan to recruit them
120
How many participants should there be?
No more than five users and running as many small test as you can afford
121
If you have enough time and money to test 15 people, for example, you are better off doing what?
You are better off conducting three test with five people each rather than one test with all 15 people
122
Definition of usability?
The definition of usability is short and sweet, how easy in Pleasant an app or sites features are to use
123
List Jacob Nelsons five components of usability?
Learn ability. Efficiency. Memorability. Errors. Satisfaction.
124
Learn ability, memorability, and efficiency require careful?
Careful recording, a large sample size, and, in the case of memorability, a repeated test with the same participant
125
Learn ability refers to what?
Learn ability refers to how easily users can accomplish basic task the first time they encounter a design. If you are creating a flash card app, for example, you might ask users to add a new flash card to a study deck and measure how easily they can accomplish the task. Learn ability is especially important when exploring new features and functionality for experimenting with novel technology.
126
Learn ability can be measured by licking at work?
I looking at success RA
127
Success rate measures what?
Success rate measures the percentage of task that users complete correctly

You will rank the task completion for a given task as what?
You will rank the task completion for a task as S (success), F (failure), or P (partial success)
129
Success rate?
(S + (P x .5)) / total number of task attempts = success rate %
130
Give an example of this formula?
For example, if you collected 32 task attempts, 16 were a success (S), and 8 were a partial success (P), then your equation would look like this: (16 + (8 x .5)) / 32 = 62.5% success rate
131
Three click rule?
The three click rule, stating that a user of the website should be able to find any information with no more than three mouse clicks
132
Efficiency is measured by what?
Efficiency is measured by Time on task, the average amount of time it takes for participants to complete a given task
133
Memorability?
Efficiency is measured by time on task, the average amount of time it takes for participants to complete a given task
134
Hey usability test script?
I usability test strip, is the name suggest, is an outline of what you plan to say and communicate to your test participant. Scripps are incredibly useful and an important part of conducting an effective usability test
135
List the four benefits of a test script?
Provide structure. Keeps test consistent. Allows for multiple facilitators. Enables remote and/or third-party facilitators
136
Provide structure?
Provides structure to the conversation so the facilitator does not forget any critical information
137
Keeps test consistent?
Keeps test consistent. This is critical so that researchers can compare results across multiple test
138
Allows for multiple facilitators?
Allows for multiple facilitators. When working in a team of researchers, a script canon sure consistency in the participant experience, since all of the researchers are reading the same introduction and questions in the same order, and so on.
139
Enable remote and/or third-party facilitators?
Enable remote and/or third-party facilitators. A script enables third-party facilitators to complete usability test for your project.
140
One of the best ways to start interpreting information from your usability test is via an?
An affinity Map
141
Another name for an affinity map?
Affinity diagram or the K-J method
142
The point of making an affinity man is to?
The point of making an affinity mouth is to isolate the very bits of information, extract them From your video or audio, and transfer them onto paper. Once these bits of information have been isolated, they can more easily be grouped, allowing you to tease our patterns of behavior or sentiment across multiple participants
143
The basic concept of an affinity map is simple?
Isolate information and determine how it relates to other bits of information
144
Fundamentally, affinity maps help designers do what three things?
Hi Seli concepts and information quickly. Visualize bits of information so that previously unseen patterns and hierarchies can emerge. Extract in group information collaboratively within a team
145
What is one common form of information architecture technique?
Card sorts
146
Name the two different types of card sorting?
One, card sorting
Two, open card shorts
147
Name three different techniques that designers use when putting a project together?
One, card sorts
Two, task analysis
Three, User flows
Taken together, these three techniques will help you create a strong foundation for the structure of your design project.
148
Card sorts?
Card sorts is a process in which participants sort relevant concepts into related groups
149
Task analysis?
Task analysis is a process in which you must closely consider the steps users must follow to complete task in your project
150
User flows?
Users flows which set out the paths that users will follow In order to achieve their goals.
