Internal Consistency

A measure of reliability; the degree to which different test items that propose to measure the same general construct produce similar results.

Odd-even Reliability

A measure of internal consistency reliability where a test is split into two parts (odd and even items) to assess the consistency of results across these halves.

Parallel Form Reliability
