Cronbach’s Alpha is a statistic that measures the reliability of tests, observations, experiments or measurements by estimating the extent to which the tests, observations, experiments or measurements provide the same results on repeated trials. Cronbach’s Alpha is a value between 0 and 1. Values near 0 indicate low reliabilty. Values near 1 indicate high reliability. (See Cronbach, 1951 and Carmines and Zeller, 1979).
