# How do you conduct predictive validity?

Contents

## What is predictive validity and its example?

## How is predictive validity evidence obtained?

To determine if predictive validity exists, we could use the following process:

1. Administer the college entrance exam to 1,000 seniors.

3. Calculate the correlation between the scores on the entrance exam and the first semester GPA.
