Chapter 6 - Validity Flashcards
Bias
As applied to tests, a factor inherent within a test that systematically prevents accurate, impartial measurement.
Central Tendency Error
A type of rating error wherein the rater exhibits a general reluctance to issue ratings at either the positive or negative extreme and so all or most ratings cluster in the middle of the rating continuum.
Concurrent Validity
A form of criterion-related validity that is an index of the degree to which a test score is related to some criterion measure obtained at the same time.
Confirmatory Factor Analysis
A class of mathematical procedures employed when a factor structure that has been explicitly hypothesized is tested for its fit with the observed relationships between the variables.
Construct
An informed, scientific idea developed or generated to describe or explain behavior; some examples of constructs include “intelligence,” “personality,” “anxiety,” and “job satisfaction.”
Construct Validity
A judgment about the appropriateness of inferences drawn from test scores regarding individual standings on a variable called a construct.
Content Validity
A judgement regarding how adequately a test (or other tool of measurement) samples behavior representative of the universe of behavior it was designed to sample.
Content Validity Ratio
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
Convergent Evidence
With reference to construct validity, data from other measurement instruments designed to measure the same or a similar construct as the test being construct-validated and that all point to the same judgment or conclusion with regard to a test or other tool of measurement.
Convergent Validity
Data indicating that a test measures the same construct as another test purporting to measure the same construct.
Criterion
The standard against which a test or a test score is evaluated; this standard may take many forms, including a specific behavior or set of behaviors.
Criterion Contamination
A state in which a criterion measure is itself based, in whole or in part, on a predictor measure.
Criterion-Related Validity
A judgment regarding how adequately a score or index on a test or other tool of measurement can be used to infer an individual’s most probable standing on some measure of interest (the criterion).
Discriminant Evidence
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 on the test being construct-validated should not theoretically be correlated.
Expectancy Chart
Graphic representation of an expectancy table.
Expectancy Data
Information, usually in the form of an expectancy table, illustrating the likelihood that an individual testtaker will score within some interval of scores on a criterion measure.
Expectancy Table
Information presented in tabular form illustrating the likelihood that an individual testtaker will score within some interval of scores on a criterion measure.
Exploratory Factor Analysis
A class of mathematical procedures employed to estimate factors, extract factors, or decide how many factors to retain.
Face Validity
A judgment regarding how well a test or other tool of measurement measures what it purports to measure that is based solely on “appearances,” such as the content of the test’s items.
