A psychology instructor wants to examine the consistency of his exam questions for his psychology course. He uses a computer program to compute the average correlation between each pair of items to compute Cronbach’s alpha, a measure of .

A measure of INTER ITEM RELIABILITY.

Explanation: inter item reliability is a type of reliability that is measured principally by a statistic called Cronbach's Alpha and ranges from 0.00 to +1.00.

Cronbach's is a name used for tau-equivalent reliability as an estimate of the reliability of a psychometric test.

It refers to the extent of consistency between multiple items measuring the same construct.

This illustrates the objective of the Psychology instructor, measuring the consistency of his exam questions. Cronbach's Alpha is used to measure consistency between multiple items using the same construct.
