Which of the following is NOT a type of reliability?

A) Split-half
B) Internal consistency
C) Cronbach's Coefficient Alpha
D) Kuder-Richardson
E) All of these are types of reliability.

Reliability

The degree to which an assessment tool produces stable and consistent results over repeated applications under the same conditions.

Cronbach's Coefficient Alpha

Cronbach's Coefficient Alpha is a statistic used to assess the internal consistency or reliability of a set of scale or test items.

Kuder-Richardson

A method of calculating internal consistency by using all the possible split-half combinations. This is done by correlating the scores for each item on the test with the total score on the test and finding the average correlation for all of the items.
