This function contains some confidence intervals for Cronbach’s alpha. The "kf" was described in Tsagris, Frangos and Frangos (2013) and stands for the method of Koning A. and Franses H. …

Properties of Cronbach’s Alpha (α) ility coefficients. Cronbach’s (1951 most commonly used reliability coefficients (Hogan, Benjamin & Brezinksi, 2000) and for this reason the properties …

here. What is Cronbach alpha? Alpha was developed by Lee Cronbach in 195111 to provide a measure of the internal consistency of a test or scale; it is exp.

To clarify these misconceptions, this paper will illustrate the computation of Cronbach Coefficient Alpha in a step-by-step manner, and also explain the meaning of each component of the SAS …

In part two, we provide a concise overview of the reliability measures before alpha. Part three covers the classical test theory (CTT), whereas part four focuses on the derivation of alpha.

In sum, Cronbach’s Alphas indicates the internal consistency, that is, the degree of interrelatedness of the items of a test (Cortina, 1993; Schmitt, 1996). Some guide-lines …
