chapter 6 part 1 Flashcards
The degree to which a test measures what it claims to measure.
Validity
The process of gathering and evaluating evidence about the validity of a test.
Validation
A research study conducted to evaluate the validity of a test.
Validation Study
A statistical measure that quantifies the relationship between a test and a criterion.
Validation Coefficient
The extent to which a test appears to measure what it is intended to.
Face Validity
The extent to which a test represents the entire domain of a construct.
Content Validity
How well a test measures the theoretical construct it claims to measure.
Construct Validity
How well a test score relates to an external standard (criterion).
Criterion-Related Validity
The degree to which a test score is related to a criterion measured at the same time.
Concurrent Validity
The extent to which test scores accurately predict future performance on a criterion.
Predictive Validity
A standard against which test scores are evaluated.
Criterion
When a criterion measure is influenced by factors unrelated to what the test is supposed to predict.
Criterion contamination
Convergent Validity – The extent to which a test correlates with other measures assessing the same construct.
Convergent Validity
Convergent Evidence – Evidence that test scores correlate with other measures of the same construct.
Convergent Evidence
Evidence showing that a test does not correlate with measures of different constructs.
Discriminant Evidence
The degree to which an additional predictor enhances the accuracy of predictions.
Incremental Validity
A logical conclusion drawn from test scores.
Inference
A statistical technique used to identify underlying relationships among test items.
Factor Analysis
Used to discover potential underlying factor structures in test data.
Exploratory Factor Analysis (EFA) –
Used to test a hypothesized factor structure.
Confirmatory Factor Analysis (CFA)
The correlation between a test item and the factor it is assumed to measure.
Factor Loading –
A table used to assess construct validity by comparing multiple traits across multiple methods.
Multitrait-Multimethod Matrix –
Systematic errors in test scores that disadvantage certain groups.
