Scales of Measurement
This scale uses numbers as labels without any quantitative value.
What is nominal?
This type of reliability assesses consistency over time.
What is test-retest reliability?
This type of validity refers to how well a test appears to measure what it claims to.
What is face validity?
This theory defines an observed score as the sum of a true score and error.
What is Classical Test Theory?
This type of test measures acquired knowledge, such as what you’ve learned in school.
What is an achievement test?
This scale ranks items but does not assume equal intervals between them.
What is ordinal?
This reliability method splits a test into two halves.
What is split-half reliability?
This type of validity is based on how well a test predicts future performance.
What is predictive validity?
This theory allows for estimating multiple sources of measurement error, such as rater and person.
What is Generalizability Theory?
This type of test is designed to predict future performance or potential.
What is an aptitude test?
This scale has equal intervals but no true zero point.
What is interval?
This coefficient is used to assess internal consistency.
What is Crohnback's Alpha?
This type of validity is demonstrated when a test correlates with other measures of the same construct.
What is convergent validity?
This is the standard error associated with predicting a criterion variable.
What is the Standard Error of Estimate?
These tests are used to assess non-cognitive traits like attitudes or preferences.
What are inventories?
This scale includes a true zero.
What is ratio?
This type of reliability involves consistency between different raters.
What is interrater reliability?
This type of validity is shown when a test does not correlate with unrelated constructs.
What is discriminant validity?
This modern theory underlies computer adaptive testing and focuses on item-level analysis.
What is Item Response Theory?
This type of test adapts the difficulty of questions based on the test taker's responses.
What is a computer adaptive test?
This type of measurement is generally superior to categorical or dichotomous measurement.
What is continuous measurement?
This theory partitions variance into multiple sources, including rater and interaction effects.
What is generalizability theory?
This type of validity ensures the test covers everything it's supposed to.
What is content validity?
This score in Generalizability Theory represents the average score across all possible conditions.
What is the universe score?
These tests are designed to be completed within a strict time limit, emphasizing how quickly they are completed.
What are speed tests?
