## How do you describe 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 predictive validity example?

Predictive validity is the extent to which performance on a test is related to later performance that the test was designed to predict. For example, the SAT test is taken by high school students to predict their future performance in college (namely, their college GPA).

## How test predictive validity can be estimated?

Predictive validity tells you how well a certain measure can predict future behavior. … This can be measured by giving tests to established scientists to see how they perform on math tests and whether there is a correlation between test scores and how well they do in their profession.

## What is the goal of predictive validity?

In the context of pre-employment testing, predictive validity refers to how likely it is for test scores to predict future job performance. Predictive validity is one type of criterion validity, which is a way to validate a test’s correlation with concrete outcomes.

## 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 difference between concurrent validity 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.

## What is a high predictive validity?

For example, the predictive validity of a test designed to predict the onset of a disease would be strong if high test scores were associated with individuals who later developed that disease.

## 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 content validity and examples?

the extent to which a test measures a representative sample of the subject matter or behavior under investigation. For example, if a test is designed to survey arithmetic skills at a third-grade level, content validity indicates how well it represents the range of arithmetic operations possible at that level.

## How do you establish content validity?

Content validity assesses whether a test is representative of all aspects of the construct. To produce valid results, the content of a test, survey or measurement method must cover all relevant parts of the subject it aims to measure.
