Cronbach's alpha

Index Cronbach's alpha

In statistics (classical test theory), Cronbach's \alpha (alpha) is the trivial name used for tau-equivalent reliability (\rho_T)Cho (2016), https://dx.doi.org/10.1177/1094428116656239 as a (lowerbound) estimate of the reliability of a psychometric test. [1]
