Cronbach's alpha can be thought of as
A)the average of the correlations between two halves of a test based on every possible split of the items into two halves.
B)the average of the largest and smallest correlations among test items.
C)the square root of the standardized path coefficient.
D)the standardized path coefficient squared.

Question

Quizplus · Accepted Answer

Cronbach's alpha is a measure of internal consistency reliability, which is the extent to which items on a test or scale are consistent in measuring the same construct. It is calculated as the average of all possible split-half correlations, where each half of the test consists of a randomly selected subset of items. Therefore, option A is correct as it provides an accurate definition of Cronbach's alpha. Option B is incorrect as it refers to only the largest and smallest correlations among test items, which is not the same as Cronbach's alpha. Options C and D refer to other statistical concepts unrelated to Cronbach's alpha.
