Validity is
- Construct validity
- Content validity
- Face validity
To be valid, the result of a test has to accurately (i.e. reliably) answer the question that the test is intended to answer.
Reliability refers to consistency of a measuring instrument. Thus, reliability is necessary but not sufficient for validity. Inverse of reliability is "random error."
Measures of reliability include inter-rater reliability, test-retest reliability, and internal consistency reliability.
