Cranbach α
Did you know?
Cronbach's alpha (Cronbach's ), also known as rho-equivalent reliability () or coefficient alpha (coefficient ), is a reliability coefficient that provides a method of measuring internal consistency of tests and measures. Numerous studies warn against using it unconditionally, and note that reliability coefficients based on structural equation modeling (SEM) or generalizability theory are in many cases a suitable alternative in certain situations.

WebJan 18, 2024 · Cronbach's alpha examines reliability by determining the internal consistency of a test or the average correlation of items (variables) within the test. In Stata, the .alpha command conducts the reliability test. For example, suppose you wish to test the internal reliability of ten variables, v1 through v10. You could run the following: WebThe general rule of thumb is that a Cronbach’s alpha of .70 and above is good, .80 and above is better, and .90 and above is best. Cronbach’s alpha does come with some limitations: scores that have a low number of items associated with them tend to have lower reliability, and sample size can also influence your results for better or worse.
