The reliability procedure that involves correlation of partial scores from one administration of one test is:

The answer to this question is the split half. Split half method of reliability is done by comparing the scores of the test that was split into two so it can measure the reliability of the scores. In this method, dividing the test items randomly into two sets can shows its reliability.

The reliability procedure that involves correlation of partial scores from one administration of one test is: Split half

Partial scores measure the degree of association between two variable. Since it came from two different variables, the reliability of this procedure is also split into two.
