Q

Explain what a Qualitative method is?

A

Qualitative method is suitable for researching “why” questions, such as why people have a specific opinion. In a qualitative method data is interpreted, categories and structured. This data is often observations, textual and figures. The qualitative approach is to observe and interpret. A qualitative analysis is thematic analysis (identifying. Analyze and interpret pattern)

Q

Explain what a Case study is?

A

Case study is a qualitative research method that entails conducting a comprehensive examination of a specific case, which could pertain to an individual, a group, or an organisation. It is used to gain a detailed understanding of a specific case or cases. Case studies often take a holistic approach, considering multiple aspects of the case rather than focusing on just one variable or factor.

Explain what an interview is in the context of a Qualitative method?

A

An interview is a qualitative research method that relies on asking questions in order to collect data. Interviewing people is at the heart of qualitative research.
There are several types of interviews:
* Structured interviews have predetermined questions asked in a predetermined order.
* Unstructured interviews are more free-flowing.
* Semi-structured interviews fall in between.

Q

What is Technical action research (TAR)

A

Technical action research refers to a systematic approach where practitioners, often in technical fields such as computer science, engage in research activities to solve practical problems or improve processes within their professional domains. The researcher wants to learn something about a technique by using it to solve a client’s problem

Q

Contrasting TAR with AR in information system

A

AR in information systems
- Identify problem in an organization
- Jointly search for a solution and implement it
- Evaluate
- Specify learning
TAR is technology-driven, not problem driven!
- The technology is motivated by a desire to solve a class of problems
- Not a singular problem in a specific situation

In action research the researcher wants to solve a problem for a client, in technical action research the problem is only a way to learn about a specific technique

Q

Describe the literature review process?

A

The literature review process involves systematically searching and critically evaluating existing literature relevant to a specific research topic.
Some steps that make a good literature review are:
Clearly defining scope and purpose: Determine the specific research topic you want to explore and establish the boundaries of your review (e.g., timeframe, geographical scope, types of sources).
Search for Relevant Literature: Use academic databases, library catalogs, and search engines to identify relevant literature. Employ a combination of Search terms, keywords, and strings, Quality criteria, Assessment and ranking functions.
Organize and Synthesize Information: Organize the selected sources chronologically based on common themes, topics, or key concepts. Identify patterns, trends, and gaps in the literature, and synthesize the findings to develop a coherent narrative that addresses your research question.
Write the Literature Review: Write the literature review using a clear and structured format. The review should be well organized and replicable.

Some steps that make bad literature review are:
Lack of Focus: A bad literature review may lack a clear focus or research question, resulting in a broad and unfocused review of the literature. Without a specific focus, the review may cover irrelevant topics, leading to confusion and lack of coherence.
Poor Organization: An ineffective literature review may suffer from poor organization, with sources arranged in a careless manner. This can make it difficult for readers to follow the text or identify key themes and trends within the literature.
Lack of Depth: A shallow literature review may provide only superficial coverage of the existing literature, failing to delve deeply into key concepts, theories, or empirical findings. This lack of depth can undermine the credibility and rigor of the review.
Lack of Critical Analysis: A weak literature review may lack critical analysis or evaluation of the sources reviewed. Instead of critically assessing the strengths, weaknesses, and limitations of each source, the review may simply summarize or describe the findings without offering meaningful insights or interpretations.
Existence of Previous Reviews: If comprehensive literature reviews already exist in the field, conducting another review without adding new perspectives or insights may be redundant and unnecessary.

57
Q

What is an experminet?

A

A test under controlled conditions that is made to demonstrate a known truth, examine the validity of a hypothesis, or determine the efficacy of something previously untried.

58
Q

When and why would an experiments be conducted?

A

When we need to identify dependable relationships between a cause and its effects. When we need to identify conditions under which such causal relationships hold. Experiments are important for many societal challenges across domains, like engineering (how flexible is this metal?)

59
Q

Challenges of conducting
experiments

A

Choice of experimental design. Interpretation of the results Statistics
Identifying and tackling validity threats

60
Q

What is a cause?

A

Most causes are more accurately called inus conditions. Presence of a match → forest fire? Any given effect often requires many factors to occur, but we rarely know all of them, or how they relate to each other.

As a consequence, many causal relationships: are probabilistic rather than deterministic in a strict sense
are not universal, but occur only under some conditions or in certain
contexts

61
Q

Causality

A

It is rare that causal relationships hold under all conditions with all types of people and at all historical time periods. It is vital to identify relationships that hold more consistently.

62
Q

Effect – what is an effect?

A

An effect can be understood as the difference between what actually happened (the fact) and what would have happened if a specific cause had not occurred (the counterfactual).

Effect: The effect is essentially the difference between what actually happened (fact) and what would have happened if the cause had not occurred (counterfactual).

63
Q

What is a causal relationship?

A

The cause preceded the effect. The cause was related to the effect. We can find no plausible alternative explanation for the effect, other than the cause

In experiments we: Manipulate the presumed cause (and observe the outcome) Observe whether variation in the cause is related to variation
in the effect Attempt to rule out other explanations of the effect

64
Q

Correlation does not imply causation

A

We may not know which variable came first (i.e., whether the presumed cause preceded the effect). We cannot rule out alternative explanations. If there exists a third variable that causes the effect, this is called a confounding variable, or simply confound.

65
Q

INDEPENDENT VARIABLE

A

This is the variable that is manipulated by the experimenter the variable that can change

We want to know if the independent variable affects the dependent variable in some way.

66
Q

DEPENDENT VARIABLE

A

This is the variable that is measured by the experiment It depends on the independent variable. Effect (result of experiment).

The dependent variable is the variable that is observed and measured to see if it is affected by changes in the independent variable.

67
Q

Hypotheses

A

A hypothesis is a precise problem statement that can be directly tested through an empirical investigation.

Example: “The iOS virtual keyboard is faster and more accurate
than the Android virtual keyboard.”

68
Q

Randomization

A

A true experiment must have randomization. Random assignment is intended to create units that are probabilistically similar to each other on average

Example: Every individual has the same chance to end up in a given condition. Therefore, any observed differences in outcome are likely to be due to the treatment (= cause)

69
Q

Simulations

A

Simulation refers to the process of creating and analyzing a model of a real-world system to gain insights into its behaviour or performance.

It involves using a computer program to replicate a complex system’s essential features and dynamics, allowing researchers to observe, experiment, and make predictions in a controlled and virtual environment.

70
Q

Key aspects of simulations

A

Modeling: Constructing a representation of the real-world system orphenomenon using mathematical equations, algorithms, or computer programming.
Manipulation: Changing variables or parameters in the simulated
environment to observe their effects on the system’s behavior.
Analysis: Collecting and interpreting data generated by the simulation to draw conclusions about the real-world system.
Prediction: Extrapolating the simulation results to make predictionsabout the future behavior or outcomes of the real-world system under different conditions.

71
Q

Confounding variable

A

A variable that is not controlled but can affect the dependent variable.

72
Q

Control Variable

A

A control variable is a circumstance (not under investigation) that is kept constant while testing the effect of an independent variable

More control means the experiment is less generalizable (i.e., less applicable to other people and other situations)

73
Q

Within-subjects

A

Each participant in a survey is tested on each condition/question

Within-subjects advantages:
Fewer participants
Less “variation due to participants”
No need to balance groups (because there is only one group!)

74
Q

Between-subjects

A

Each participant in a survey is tested on one condition/question only

Between-subjects disadvantage
More participants (harder to recruit, schedule, etc.)
More “variation due to participants”
Need to balance groups (to ensure they are more or less the same)

75
Q

Validity threats in research

A

Validity threats refer to factors that can compromise the validity of the research findings.

Internal validity threats ( researcher’s ability)
- Reasons why inferences (assumption) that the relationship between two variables is causal may be incorrect
External validity
- Reasons why inferences about how study results would hold
over variations in persons, settings, treatments, and outcomes
might be incorrect.

76
Q

What is SURVEYS

A

Any means of asking people for information

77
Q

What are some Survey characteristics

A

Surveys can be a paper or web-based, participants answer the questions on their own
- No chance to clarify or ask follow-ups
- It is hard to know how questions are interpreted
- Once the survey is out it is out

78
Q

In what cases are Surveys used?

A

We use surveys when we need to investigate a clearly defined topic that involves measuring
- Knowledge
- Opinions
- Behaviours
- Perception

79
Q

What to think about when developing a survey?

A

We need our surveys to have a few important properties
- Relevant to our research questions
- Easy to interpret
- Be interpreted in the same way by all participants

general steps to survey development
- Define variables to measures
- Develop/adapt/find appropriate questions to measure those
- Validate and pilot

80
Q

Variable definition and survey Questions

A

The first step in developing a survey is to define variables. Then, come up with questions to measure those variables. Often we use several questions for the same variable, to capture different aspects of the variable topic
These questions can be:
- Knowledge questions
- Likert scale questions

When developing questions there are some things to consider
- Clarity
- Consistency
- Question order
- Response order

81
Q

Validation and Piloting

A

Validity concerns how well the survey measures what it intends to
measure
Expert review is one typical approach
- Focus on validity
- Ask domain experts about the survey questions (supervisor, peers)
Reliability concerns how consistently it does that
Distribute the survey to a small set of respondents and test how it goes
- Typically adding a comment question
- Focus on reliability (are people answering as expected

82
Q

Survey Sampling

A

Our target group is called population - and we can typically not ask everyone in that population. Instead, we need to draw a sample. A sample is a subset of our population which we assume to be representative of the population at large.

83
Q

Random Sampling

A

Random sample
- We sample at random, and give everyone an equal chance of being selected
- Practically, we could select names at random from a list of everyone in the population
- Gold standard – but expensive and often infeasible

84
Q

Stratified sampling

A

Stratified sampling (a practical approach to random sampling)
- The population is split into sub-population based on criteria such as age, gender….
- A random sample is drawn from each sub-population
- Intends to ensure a greater spread over the population

85
Q

Convenience sampling

A

Convenience sampling
- Aka accidental sampling or opportunity sampling
- Involves recruiting participants “close at hand”
- Includes asking your friends, using social media, etc
- We cannot know how representative the sample is of the target population

86
Q

Purposive sampling

A

Purposive sampling
- Selective sampling where “high-value” respondents are invited to answer
- The idea is to include participants who are likely to generate valuable data
- Useful in some cases, but hard to generalize from the results

87
Q

Bias in Surveys

A

Sampling bias is skewness in results due to improper sampling.

Confirmation bias
- Participants tend to agree rather than disagree with opinions
- Try to avoid opinionated questions
Question order bias
- Question order may impact how participants answer
- Randomize questions to avoid
Survey fatigue bias
- Participants may get fatigued and stop answering properly
- Limit the survey length

88
Q

In Data Analysis researcher may impact the results. True/False?

A

True
