How do you interpret predictive validity?

In psychometrics, predictive validity is the extent to which a score on a scale or test predicts scores on some criterion measure. For example, the validity of a cognitive test for job performance is the correlation between test scores and, for example, supervisor performance ratings.

How do you explain predictive validity?

Predictive validity is the degree to which test scores accurately predict scores on a criterion measure. A conspicuous example is the degree to which college admissions test scores predict college grade point average (GPA).

What is a good predictive validity?

For example, the SAT test is taken by high school students to predict their future performance in college (namely, their college GPA). If students who scored high on the SAT tend to have high GPAs in college, then we can say that the SAT has good predictive validity.

How are the test results of predictive validity interpreted?

Predictive validity indicates the extent to which an individ- ual’s future level on the criterion is predicted from prior test performance. Concurrent validity indicates the extent to which the test scores estimate an individual’s present standing on the criterion.

What is the goal of predictive validity?

Predictive validity tells you how well a certain measure can predict future behavior. One of the most common uses for predictive validity is in University Admissions. Grade Point Average, SAT/ACT scores and other criterion are used to predict a student’s likely success in higher education.

How do you use predictive validity?

Definition of Predictive Validity:

The best way to directly establish predictive validity is to perform a long-term validity study by administering employment tests to job applicants and then seeing if those test scores are correlated with the future job performance of the hired employees.

How can predictive validity be improved?

  1. The study also found that predictive validity could be improved by breaking the overall sample down into the various faculties that students registered in, thereby grouping students based on general area of study (Kennet-Cohen, et al., 1999). …

What is the difference between concurrent and predictive validity?

Concurrent validity is demonstrated when a test correlates well with a measure that has previously been validated. … The two measures in the study are taken at the same time. This is in contrast to predictive validity, where one measure occurs earlier and is meant to predict some later measure.

Is predictive validity reliable?

Despite this weakness, predictive validity is still regarded as an extremely powerful measure of statistical accuracy. In many fields of research, it is regarded as the most important measure of quality, and researchers constantly seek ways to maintain high predictive validity.

Why is predictive validation difficult?

One of the most important problems associated with evaluating the predictive validity of a selection test is that the outcome variable is only known for the selected applicants. … It is almost always going to be the case that there will be rejected candidates who will not have an outcome score.

What is predictive evidence?

evidence that a test score or other measurement correlates with a variable that can only be assessed at some point after the test has been administered or the measurement made. Also called predictive criterion-related validity; prospective validity. …
