Internal Validity

Internal Validity

1. Face validity - Whether a measure appears, at face value to be actually measuring what it says it is.

2. Criterion Validity - Whether a phenomenon measured in one way will relate to another (related variable).

3. Concurrent Validity - This is a type of criterion validity and concerns whether a measure will produce a similar score for a particular individual as another test that claims to assess the same phenomenon.

4. Construct Validity - This looks are whether a measure is based on some certain-to-exist phenomenon, which it is testing.
