Q

T/F
It is called an operational definition because it clearly describes the operations that are not directly involved in manipulating or measuring the variables in an experiment.

Q

T/F
operational definitions are equally important when we are working with variables that can be observed more directly.

A

True

18
Q

T/F
operational definitions are equally important when we are working with variables that can be observed more directly.

A

True

19
Q

It means consistency and dependability.
Good operational definitions are reliable

A

Reliability

20
Q

This estimates that are used to evaluate the error associated with administering a test at two different times.

A

Test-retest reliability

21
Q

T/F
test-retest reliability measures traits that does not change over time

A

True

22
Q

T/F
Ideally, six months or more interval. When interval between testing is more than six months, referred as coefficient of stability.

A

True

23
Q

T/F
You can use test that are different in difficulty when using alternate forms

A

False

24
Q

T/F
Split half form provides a measure of the internal consistency of the test, helping ensure that the test items consistently measure the intended construct.

A

TRUE

25
Q

Refers to the degree of correlation among all the items on scale.

A

Inter-Item Consistency

26
Q

the degree of agreement or consistency between two or more scorers (or judges or raters) with regard to a particular measure.

A

Inter-rater reliability

27
Q

It is a judgment of how well a test measures what it needs to measure

A

Validity

28
Q

The judgment about the items appropriateness is made by test taker rather than expert in the domain.

A

Face Validity

29
Q

It is the type of validity that is
important whenever a test is used to make inferences about the broader domain of knowledge and or skills
represented by a sample of items.

A

Content Validity

30
Q

Refers to how well a test or tool measures the construct that it was designed to measure

A

Construct Validity

31
Q

Convergent validity is a measure correlating to the different constructs.

A

False. same construct

32
Q

Measure correlating to different
constructs.

A

Divergent Validity

33
Q

T/F
criterion related validity compares the result of the new test to the established test to assess how the new test measures the same variable.

A

True

34
Q

T/F
Predictive validity assesses the ability of a test to predict future outcomes. By examining the correlation between test scores and future criterion measures, researchers can determine the extent to which the test accurately predicts future performance or behavior.

A

True

35
Q

T/F
Concurrent validity assesses the extent to which a test score is related to a criterion measure obtained at the same time.

A

True

36
Q

It is the degree to which changes in the
dependent variable across treatment conditions were due to the independent variable.

A

Internal Validity

37
Q

T/F
Internal validity establishes a regression relationship between the independent and dependent
variable.

A

False. cause and effect relationship

38
Q

T/F
Changing of instrument being used in experiment can not affect the result of the experiment

A

False

39
Q

Occurs when subjects drop out of experimental conditions at different rates.

A

Subject mortality

40
Q

T/F
Methodology section provides the reader with sufficient detail (who, what, when, and how) to exactly replicate your study.

A

True
