W2 - Chapter 6 - Validity (DN) Flashcards
1
Q
base rate
A
- an index
- usually expressed as a proportion of the extent to which a particular trait, behaviour, characteristic, or attribute exists in a population
p. 193, 219
2
Q
bias
A
- as applied to tests
- a factor inherent in a test which systematically prevents accurate, impartial measurement
p. 204-206
3
Q
central tendency error
A
- a type of rating error
- a rater exhibits a general reluctance to rate at either the positive or negative extreme
- so all or most ratings end up in the middle of the rating continuum
p.205
4
Q
concurrent validity
A
- a form of criterion-related validity
- an index of the degree that a test score relates to some criterion measure obtained at the same time (concurrently)
p. 190, 191-192
5
Q
confirmatory factor analysis (CFA)
A
- class of mathematical procedures
- employed when an explicitly hypothesised factor structure is tested for its fit with an observed relationship between variables
p. 203, 345
6
Q
construct
A
- an informed, scientific idea developed or generated to explain behaviour
- e.g., ‘intelligence’, ‘personality’, anxiety, and ‘job satisfaction’
p.119, 198
7
Q
construct validity
A
- a judgement about the appropriateness of inferences drawn from test scores
- regarding individual standings on a variable (construct)
p.198-204
8
Q
content validity
A
- a judgement regarding how adequately a test samples behaviour representative of the universe of behaviour it was designed to measure
p. 184-189
9
Q
content validity ratio (CVR)
A
- a FORMULA developed by C. H. Lawshe
- used to GAUGE AGREEMENT among RATERS regarding how ESSENTIAL an INDIVIDUAL TEST ITEM is for INCLUSION in a test
p. 187-188
10
Q
convergent evidence
A
- with reference to CONSTRUCT VALIDITY
- data from OTHER MEASUREMENT INSTRUMENTS designed to measure THE SAME or SIMILAR CONSTRUCT (as the test being ‘CONSTRUCT-VALIDATED’)
11
Q
convergent validity
A
- data indicating that a test measures THE SAME CONSTRUCT as ANOTHER TEST purporting to measure the SAME CONSTRUCT
p. 202n3
12
Q
criterion
A
- the STANDARD against which a test or test score is EVALUATED
- this standard may take many forms
- (e.g., a specific BEHAVIOUR, or SET of BEHAVIOURS)
p.139, 190, 421
13
Q
criterion contamination
A
- a state in which a CRITERION MEASURE is ITSELF based, in whole or in part, on a PREDICTOR MEASURE p.190
14
Q
criterion-related validity
A
- a JUDGEMENT regarding how ADEQUATELY a score or index on a test, or other measurement tool CAN be used to INFER an individual’s MOST PROBABLE standing on some measure of interest (the criterion) p. 190-198
15
Q
discriminant evidence
A
- with reference to CONSTRUCT VALIDITY - DATA from a test or other measurement instrument SHOWING LITTLE RELATIONSHIP between test scores or other VARIABLES with which the scores should NOT theoretically be correlated; contrast with convergent evidence - In other words - there is little/no relationship where little/no relationship is expected! p.202-203
16
Q
expectancy chart
A
- graphic representation of an EXPECTANCY TABLE p.196
17
Q
expectancy data
A
- information, usually in the form of an EXPECTANCY CHART - illustrates the likelihood that an INDIVIDUAL TESTTAKER will score WITHIN some INTERVAL of SCORES on a CRITERION MEASURE p.196-198, 219,229
18
Q
expectancy table
A
- information presented in TABULAR FORM - illustrates the likelihood that an INDIVIDUAL TESTTAKER will score WITHIN some INTERVAL of SCORES on a CRITERION MEASURE
19
Q
exploratory factor analysis
A
- a class of MATHEMATICAL PROCEDURES - they are employed to ESTIMATE FACTORS, EXTRACT FACTORS, or DECIDE HOW MANY FACTORS TO RETAIN p.203
