The above calculation of coefficient of Cronbach's Alpha was carried out to test the instruments reliability, the methodology opted to determine and statistically calculate Cronbach's Alpha. It provides proportion of variance estimation in the test scores that can be attributed to true score variance. Cronbach's Alpha is
.869 for 10 items which indicates that the 86% items have relatively high internal consistency. According to Sattler, .60 is lowest and considered as unreliable, .70 is considered relatively reliable and .80 and .90 is highly acceptable. (Note that a reliability coefficient of .70 or higher is considered “acceptable" in most social science research situations.)
The Second step carried out in the data analysis was to check whether the sample size is appropriate with number of variables taken for the study. In this regard, we have used KMO and Bartlett's Test. KMO measures the sampling adequacy (which should be greater than 0.5) for a successful factor analysis. Bartlett's test is another indicator to measure the strength of relationship among variables.
