• Construct validity: Does the test measure the concept that it’s intended to measure?

What is the difference between validity and reliability?

Reliability and validity are both about how well a method measures something: Reliability refers to the consistency of a measure (whether the results can be reproduced under the same conditions). Validity refers to the accuracy of a measure (whether the results really do represent what they are supposed to measure).

How do you test content validity?

Expert judgement (not statistics) is the primary method used to determine whether a test has content validity. Nevertheless, the test should have a high correlation w/other tests that purport to sample the same content domain.

What makes good internal validity?

Internal validity is the extent to which a study establishes a trustworthy cause-and-effect relationship between a treatment and an outcome. The less chance there is for “confounding” in a study, the higher the internal validity and the more confident we can be in the findings.
