Questions and Answers

What does meta-analysis refer to in the context of validity evidence?

  • A technique to measure decision accuracy
  • A single study evaluating the validity of a personnel test
  • A method for combining research results from a large number of studies (correct)
  • A method for designing new research studies

    • What is the purpose of evaluating the accuracy of decisions in the context of tests and decisions?

  • To design new personnel tests
  • To determine the base rate of the population
  • To measure the effect of a test on decision accuracy
  • To compare predictions with the outcome of decisions (correct)

    • What represents accurate decisions in the context of tests and decisions?

  • False positive and false negative
  • Criterion and predictor measures
  • True positive and true negative (correct)
  • Base rate and sample size

    • Why might there be a need for meta-analysis when evaluating validity?
