Experimental Methods And Measures

Question 1

This experimental method generate numerical data that are categorized, ranked, or used to construct graphs and draw statistical conclusions

Answer 1

Quantitative experimental method

Question 2

This type of experimental method produce results that are not numbers rather it could be words, opinions, observations, or anything else not numerical (cannot be easily quantified). These are more open ended an dexploratory and can be used later to develop a quantitative test

Answer 2

Qualitative experimental method

Question 3

Research methods that include the quantitative and qualitative results

Answer 3

Mixed research methods

Question 4

These types of methods are in bias and fact based

Answer 4

Objective measures

Question 5

These measures are subject to opinion

Answer 5

Subjective measures

Question 6

This refers to the extent to which studies results are both genuine and generalizable

Answer 6

Validity

Question 7

Three types of validity

Answer 7

Internal, external, test

Question 8

This type of validity describes the extent to which we can draw causal conclusions from the study data

Answer 8

Internal

Question 9

If you cannot conclusively determine that causation explains this relationship we have served our study last what validity?

Answer 9

Internal

Question 10

An outside factor not being studied but impact both variables under consideration

Answer 10

Confounding variable

Question 11

This type of validity depends on how much we can minimize confounding variables

Answer 11

Internal validity

Question 12

This validity refers to the extent to which we can generalize our results in two different experimental situations or real life

Answer 12

External validity

Question 13

Type of validity which describes how well a research design was able to test what it intended to test

Answer 13

Test validity

Question 14

This is how well the test covers the full scope of content that the researchers intend to measure

Answer 14

Content test validity

Question 15

This tells us whether our test actually assesses the construct we assigned it to test

Answer 15

Construct test validity

Question 16

This describes how well our test correlates with some other well respected criterion, like an established alternate test of the same measure

Answer 16

Criterion test validity

Question 17

This gives us a good way to determine whether a new test can be trusted

Answer 17

Criterion Test validity

Question 18

This measures how well our test predicts later scores on some chosen measure

Answer 18

Predictive test validity

Question 19

The extent to which study results are consistent

Answer 19

Reliability

Question 20

This answers the question if we do the study again, will we see similar results?

Answer 20

Reliability

Question 21

The extent to which measurements agree within an experiment. How close the data points are

Answer 21

Precision

Question 22

The extent to which measurements agree with standard values. The closer a result is to the correct value, the more ________ that result is

Answer 22

Accuracy

Question 23

A reliable experiment is expected to produce what results?

Answer 23

Precise results

Question 24

A valid experiment is expected to produce what results?

Answer 24

Accurate results

Question 25

Repeating the experiment yields inconsistent values. Not close to true value.

Answer 25

Unreliable an invalid experimental study

Question 26

Involves data points that are closely clustered around an inaccurate value

Answer 26

Reliable and invalid experimental study

Question 27

In this scenario our results are all over the place but the average of the wildly inconsistent results is close to the standard measure

Answer 27

Unreliable and valid

Question 28

This method collect large amount of data and often take the form of questionnaires

Answer 28

Survey methods

Question 29

This scale consist of a statement, followed by continuum of possible responses from 1 to 5 or from 1 to 10, Usually ranging from strong agreement with a statement to strong disagreement.

Answer 29

Likert scales

Question 30

Is a form of self report and often use Likert scales

Answer 30

Questionnaires

Question 31

Biases Inherent to survey methods

Answer 31

Self reporting bias

Question 32

Tendency of respondents to answer in a way that they think makes them look socially successful.

Answer 32

Social desirability bias

Question 33

The tendency to answer “yes” when uncertain

Answer 33

Acquiescence bias
