WebCronbach’s alpha coefficient is most commonly used to interpret internal consistency - meaning it measures the proportion of variance that is systematic or consistent in a set of test scores (Brown, 2002).. In the research community, an appropriate Cronbach’s alpha coefficient is between 0 to 0. WebReliability coefficients are variance estimates, meaning that the coefficient denotes the amount of true score variance. This is unlike a standard correlation coefficient where, …
