Ms Eppp Test Construction Questions And
Answers
Interscorer reliability Measured by Kappa coefficient, measure of the agreement b/w 2
judges who each rate a set of objects using nominal scales
Standard error of measurement How much error an individual test score can be expected
to have; used to construct confidence interval
Spearman-Brown formula Applied to estimate the effects of lengthening or shortening a
test on its reliability
Criterion contamination In the process of validating a test, predictor scores influence any
individual's criterion status
Content validity Extent to which test items adequately sample the content area to be
measured (math test measures what was taught in class)
Criterion-related validity Predicting an individual's behavior in specified situations (job
performance)
Criterion-related validity coefficient Used to determine correlation b/w predictor and
criterion. Measured by Pearson r, ranges b/w -1 & +1
