PSYCH 499 Lecture Notes - Lecture 4: Convergent Validity, Face Validity, Agreeableness
Document Summary
Predictor: any variable used to forecast a criterion: e. g. barometric pressure is used to forecast rainfall. Divide items into odd- and even-numbered items two sets of scores are correlated if the test is internally consistent, should have high degree of similarity between responses (number of right/wrong answers: cronbach"s alpha or kuder-richardson 20 (kr20) Each test item is treated like a minitest response of each item is correlated with the response of all the other items average is related to the homogeneity of the test. Assessing the quality of predictors validity and faithful measure of the construct it purports to measure. Validity: a standard for evaluating tests that refers to the accuracy or appropriateness of drawing inferences from test scores. Assess construct validity by assess links between x and construct 1, and y and construct 2 relationship between the two constructs can be used for constructing theories of job performance.
