16 Questions
What does meta-analysis refer to in the context of validity evidence?
A method for combining research results from a large number of studies
What is the purpose of evaluating the accuracy of decisions in the context of tests and decisions?
To compare predictions with the outcome of decisions
What represents accurate decisions in the context of tests and decisions?
True positive and true negative
Why might there be a need for meta-analysis when evaluating validity?
Because a large number of studies rarely use precisely the same tests and criterion measures
What should be considered in order to fully evaluate the effect of a test in the context of tests and decisions?
Both base rate and sample size
What is the purpose of validity evidence from meta-analyses?
To evaluate the criterion-related validity
What is the base ratio in the context of tests and decisions?
The proportion of successful applicants in the applicant pool
How does the selection ratio influence the proportion of success?
Lower selection ratio means a test's validity has less influence
When decisions are made on a random basis, what is the probability of true positive decisions with a base rate of .60 and a selection ratio of .50?
30%
What happens to the probability of true positive decisions as the validity coefficient of a test increases?
It increases
According to Utility Theory, what two things should be considered to evaluate a test's impact on decisions?
The ability to increase the number of correct decisions and the value of correct decisions
What does the term 'productivity gain' refer to in the context of evaluating the effect of a test?
The amount of money gained if a test is used
In a validation study for a measure of human behavior, what statistical analyses should be included in the plan?
Reliability and construct validity testing
When making decisions based on a valid test, what happens if the validity coefficient is equal to 0.0?
The probability of TP is exactly the same as when decisions are made at random.
What represents accurate decisions in tests and decisions context according to Utility Theory?
Decisions based on a valid test
What is the best base ratio for test use in decisions according to the text?
Base ratio of .50
Test your understanding of validity for decisions, criterion-related validity, and evidence from meta-analyses in Validity II Chapter 9. Explore the concepts of construct and criterion-related validity and their application in success prediction.
