WebCronbach’s Alpha Cronbach‟s alpha is perhaps the most common estimate of internal consistency of items in a scale (Cronbach, 1951; Cronbach & Shavelson, 2004). Alpha measures the extent to which item responses (answers to survey questions) correlate with each other.

WebThe Alpha-Cronbach assessment was widely used after a discussion by Cronbach, who suggested using the Cronbach alpha value rather than the Kuder-Richardson formula (KR-20), which has been used in measurements (Cronbach, 1951). Cronbach's alpha value is considered ideal and acceptable if it ranges from 0 to 0 (Terwee et al., 2007).
WebTo overcome this problem, Cronbach (1951) came up with a measure that is loosely equivalent to splitting data in two in every possible way and computing the correlation coefficient for each split.
