Definitions:

Coefficient Alpha

Coefficient Alpha, often denoted as Cronbach's alpha, is a measure used to assess the reliability, or internal consistency, of a set of scale or test items.

Internal Consistency Reliability

A measure of how well the items in a test measure the same concept or construct, indicating the extent to which all items in a test contribute equally to the final score.

Parallel Forms Reliability

The consistency of scores on two different but equivalent forms of the same test, assessing the consistency of results over different versions of instruments.

Test-Retest Reliability

The consistency of a measure or test over time when administered to the same individuals under identical conditions.
