Measurement Theory in Action: Case Studies and Exercises comprises twenty modules, each corresponding to entire chapters in typical measurement theory texts. The modules begin with introductory concepts and a review of statistics; progress through conceptions of content, criterion-related, and construct validation, validity generalization and test-bias; and conclude with more advanced topics such as multiple regression and item response theory (IRT). Each module is composed of an overview, case studies, exercises, Internet references, and suggested further readings. An extensive glossary of key terms is also provided for quick reference. An Instructor's Resources CD containing exercises and assignments is also available.
Module 7: Criterion-Related Validation
If the purpose of validation is to examine whether the inferences and conclusions based on test scores are defensible, just how does the criterion-related approach provide this information? The answer is relatively straightforward. The criterion-related approach to test validation involves examining the empirical relationship between scores on a test and a criterion of interest, typically by use of a correlation coefficient. The appropriate choice of a criterion will depend on what inferences we hope to make. Thus, in determining the validity of a college entrance exam, we would desire a criterion of college success. In determining the validity of an employment selection exam, we would want a criterion of successful job performance. Moreover, in examining the success of a new type of ...
