Question 1

Integrator reliability

Answer 1

Two or more individuals should make an observation or one observer should examine the behavior on more than one occasion

Question 2

Validity

Answer 2

Measure accurately = does the instrument measure what it claims to measure?

Question 3

Content validity

Answer 3

Criterion related, construct

Question 4

Concurrent validity

Answer 4

Degree of correlation between two measures

Question 5

Predictive validity

Answer 5

Measure of concept and some future measure of the concept

Question 6

Face validity

Answer 6

Refers to expert verification that the instrument measures correctly

Question 7

Construct validity

Answer 7

Test measures a theoretical construct or trait

Question 8

Divergent validity

Answer 8

Differentiates one construct from others that are similar

Question 9

Reliability

Answer 9

Measure consistently

Question 10

Stability

Answer 10

Homogeneity or internal consistency, equivalence

Question 11

Reliability coefficient

Answer 11

Measures the relationship between error variance, true variance, and the observed score

Question 12

Parallel reliability

Answer 12

Using two comparable forms of an instrument to test the same concept

Question 13

Integrator reliability

Answer 13

Two or more investigators are collecting data

Kappa level of 0.9 is good

Question 14

A measure can be considered to be reliable while…

Answer 14

Unlikely found to be valid

Question 15

Error variance

Answer 15

The differences in scores between actual measurement of behavioral changes and thee extent of variability in test scores

Question 16

Chance error

Answer 16

Variability of scores due to random confounding variables

Question 17

Test score

Answer 17

Error variance plus the true score

Question 18

Constant error

Answer 18

Answering in a socially desirable way (validity effected)

Question 19

Chronbachs alpha

Answer 19

Most common test to study validity

Measures the homogeneity of an instrument with a like-type format

Question 20

Split half

Answer 20

Provides a measure of consistency in terms of sampling the content

Question 21

KR-20

Answer 21

Estimate of homogeneity used for instruments that have a dischotomous response format (yes/no)

Coefficient of 0.1 shows no correlation among the error variance, true variance or observed variance

Question 22

Equivalence

Answer 22

Consistency or agreement among observers using the same measurement instruments

Parallels or alternate form

Question 23

Test-retest

Answer 23

Test of stability

The lower the coefficient the lower the correlation

Does not prove measurement error
