Goodbye Cronbach’s alpha! I found more reliable than you...
Many researchers in psychometrics argue that Cronbach’s alpha (1951) is not an adequate measure of reliability. It is with the idea to improve data analysis practices that this short article will present the theoretical foundations of reliability, summarize the main limits of Cronbach’s alpha, and concisely present two promising alternatives: great lower bound and omega. Open softwares are mentioned to show how to obtain an estimate of these coefficients.
