When the entire scale points to the same direction, you can compute the overall Cronbach Coefficient Alpha. In this example, the standardized Cronbach Coefficient Alpha is .85. It is a good sign if the entire instrument is considered one scale. However, this instrument carries seven subscales. A high Alpha indicates that all response patterns are internally consistent. In social science, Cronbach's Alpha > 0.7 is considered as acceptable. The Cronbach's Alpha in this example is 0.671, less than the standard but it is still high. Since the calculation of Cronbach's Alpha depends on the inter-correltation, this table shows which question has low correlation.2020 polaris sportsman 450 graphics kit.
