Cronbach’s Alpha: Simple Definition, Use and Interpretation
Cronbach’s alpha (or coefficient alpha), developed by Lee Cronbach in 1951, is a way to measure reliability, or internal consistency of a psychometric instrument. “Reliability” is how well a test consistently measures what it is supposed to measure. Low reliability would mean it’s measuring something else, or possibly nothing at all.
