Answer 1

Reliability
- A baseball player’s batting average doesn’t change much over the course of the season. (consistent/stable measure)
- A student tries retaking the SAT, but his new score is similar to his old one. (test–retest consistency)

Validity
- A basketball coach measures her players’ ability to shoot free throws by seeing how far they can throw a football. (not a valid measure of free-throw ability)
- High scores on a test for aptitude in engineering correlate well with later success in the field. (predictive validity)
