Internal consistency reliability refers to how well the items that make up an instrument (for instance, a test or survey) reflect the same construct. Two simple measures of internal consistency are most useful for tests made up of multiple items covering the same topic, of similar difficulty, and that will be scored as a composite: the average inter-item correlation and the average item-total correlation. Substituting these values into the equation gives.
