Cronbach's alpha correlation

WebCronbach'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. WebJul 4, 2024 · However, in order to test internal validity I might wish to calculate Cronbach's alpha which gives a good value precisely when X1, X2 and X3 are correlated. This seems to be contradictory. To have a valid linear regression model I want to avoid variable correlations, but for the "test" to be reliable they should be correlated.
