Types of Validity Content: the test items actually represent

what you want to know (table of specifications, judges, etc.)

Concurrent: your test measures the same as a similar tests

Predictive: your test accurately predicts the outcome of something

Construct: can you use your test to make inferences? (group differentiation studies, factor analysis, etc.)



4-16

Types of Reliability Test-Retest: Give the same test twice. Alternate Forms: Give parallell or

equivalent forms of the test Internal Consistency: split the test in

half and compare the two halves Interrater: have two or more people

score the test to see if there are differences.



4-17

Reliability Coefficients Correlation coefficient (ranges 0 to 1). Ratio of true score variance to the observed score

variance Reliability = scores on your test

scores on a “perfect test” Having more items on your test provides a better

mathematical chance at a higher score. Error = 1 - reliability Your test has reliability at .85

85% of the score is accurate/ reliable 15% of the score is error



4-18

A Little History Oscar Buros: founded

the Mental Measurement Yearbook Series

Raymond Cattell: Researched intelligence (fluid vs. crystallized) and developed the 16PF
