All the possible split-half correlations are correlated and then the mean, or average, of all of these scores is obtained.

A) Content validity
B) Concurrent validity
C) Construct validity
D) Discriminant validity
E) Parallel or equivalent form reliability
F) Internal consistency
G) Predictive validity
H) Odd-even reliability
I) Test-retest reliability

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

The consistency of test scores across different versions of a test designed to be equivalent in terms of content and difficulty level.
