In the context of calculating estimates of reliability, _____ is a metric based on the average interitem correlations and the number of items on the measure.
A) the test-retest correlate
B) split-half reliability coefficient
C) coefficient alpha
D) the transient effect correlate

Question

Quizplus · Accepted Answer

Coefficient alpha, also known as Cronbach's alpha, is a metric based on the average interitem correlations and the number of items on the measure. It is commonly used as an estimate of internal consistency reliability. The other options listed, such as test-retest reliability and split-half reliability, are also measures of reliability but are not based on average interitem correlations. The transient effect correlate is not a known measure of reliability.
