      As said above, we never know the true reliability of a test. So we have to get by with estimates of reliability. Test-retest estimate. Operational Definition. 1. Give the test to a normative group. 2. Minimize memory/carryover from the first administration. 3. Give the test again to the same people. 4.

This yields two scores for each person and the correlation between these two sets of scores is the test-retest …
