Question 1

construct validity

Answer 1

extent to which evidence can be provided that test measures a theoretical constraint

Question 2

extent to which evidence can be provided that test measures a theoretical constraint

Answer 2

construct validity

Question 3

construct

Answer 3

an attribute, trait, or characteristic that in itself is not directly observable but can only be inferred by looking at observable behaviors, which are hypothesized to indicate the presence of that construct.

ex: we never really observe the construct of aggression, but we do observe behaviors that would lead us to conclude that a person might be demonstrating the construct of aggression

Question 4

an attribute, trait, or characteristic that in itself is not directly observable but can only be inferred by looking at observable behaviors, which are hypothesized to indicate the presence of that construct.

Answer 4

construct

Question 5

abstract constructs

Answer 5

underlying attitudes or attributes that exist in our imaginations (intelligence, beauty, love)

Question 6

underlying attitudes or attributes that exist in our imaginations (intelligence, beauty, love)

Answer 6

abstract constructs

Question 7

concrete constructs

Answer 7

activities that are observable and measurable

Question 8

activities that are observable and measurable

Answer 8

concrete constructs

Question 9

What are the similarities and differences between abstract constructs and concrete constructs?

Answer 9

Sim: they both measure

Diff: abstract is more theoretical while concrete is observable

Question 10

construct explication

Answer 10

defining or explaining a psychological construct

Question 11

defining or explaining a psychological construct

Answer 11

construct explication

Question 12

What is the three step process for constructor’s explication?

Answer 12

1. identify the behaviors that relate to the construct
2. identify other constructs that may be related to the construct being explained
3. identify behaviors related to similar constructs, and determine whether these behavior are related to the ongoing construct

Question 13

gathering evidence of construct validity

Answer 13

two types: theoretical evidence and psychometric evidence

this is an ongoing process, not an event

Question 14

gathering theoretical evidence

Answer 14

establish nomological network: lis the associations the construct has with other constructs

propose experimental hypothesis: propose one or more hypotheses using the test as an instrument for measuring the construct

Question 15

establish nomological network: lis the associations the construct has with other constructs

propose experimental hypothesis: propose one or more hypotheses using the test as an instrument for measuring the construct

Answer 15

gathering theoretical evidence

Question 16

gathering psychometric evidence

Answer 16

convergent evidence of validity & discriminant evidence of validity

Question 17

convergent evidence of validity & discriminant evidence of validity

Answer 17

gathering psychometric evidence

Question 18

gathering psychometric evidence: Convergent Evidence

Answer 18

shows that constructs that theoretically should be related are related; evidence that the scores on a test correlate strongly with scores on other tests that measure the same constructs

methods used to gather: ????

test correlates consistent with theory

Question 19

shows that constructs that theoretically should be related are related; evidence that the scores on a test correlate strongly with scores on other tests that measure the same constructs

Answer 19

gathering psychometric evidence: Convergent Evidence

Question 20

gathering psychometric evidence: Discriminate Evidence

Answer 20

when the test scores do not correlate with unrelated constructs

methods used to gather: correlate test scores

Question 21

when the test scores do not correlate with unrelated constructs

Answer 21

gathering psychometric evidence: Discriminate Evidence

Question 22

multitrait-multimethod design (MTMM)

Answer 22

tests for convergence across different measures of the same thing and for divergence between measures of related but conceptually distinct things

researcher chooses two or more constructs that are unrelated and two or more types of tests to measure each of the constructs

Question 23

tests for convergence across different measures of the same thing and for divergence between measures of related but conceptually distinct things

Answer 23

multitrait-multimethod design (MTMM)

Question 24

factor

Answer 24

the underlying commonalities of tests or test questions that measure a construct

What a group of test items have in common that accounts for their correlations

Question 25

the underlying commonalities of tests or test questions that measure a construct

What a group of test items have in common that accounts for their correlations

Answer 25

factor

Question 26

factor analysis

Answer 26

an advanced statistical procedure based on the concept of correlation that helps investigator to explain why two tests are correlated

Question 27

an advanced statistical procedure based on the concept of correlation that helps investigator to explain why two tests are correlated

Answer 27

factor analysis

Question 28

Differences and similarities of CFA and EFA

Answer 28

Diff:

• CFA researcher specifies in advanced what the factor should look like
• CFA can specify in advance a large number of characteristics believed to be present in the data
• CFA can specify the amount and nature of any measurement error present i the data

Sim:

• both specify the number of factors they expect to be able to extract from data
• both explain correlations between items or tests
