What is an acceptable level of reliability?
A general accepted rule is that α of 0.6-0.7 indicates an acceptable level of reliability, and 0.8 or greater a very good level. However, values higher than 0.95 are not necessarily good, since they might be an indication of redundance (Hulin, Netemeyer, and Cudeck, 2001).
Does Cronbach alpha measure reliability or validity?
In practice, Cronbach’s alpha is a lower-bound estimate of reliability because heterogeneous test items would violate the assumptions of the tau-equivalent model.

Why do we use Cronbach alpha?
Cronbach’s alpha is a measure used to assess the reliability, or internal consistency, of a set of scale or test items. Cronbach’s alpha is thus a function of the number of items in a test, the average covariance between pairs of items, and the variance of the total score.
Why is dependability important in friendship?
Being dependable and reliable tells others that their time is important and that we respect them. Our friends and family need to know that they can depend on us to be there when we say we will be there. The quality of dependability tells our friends and family members that we love them and respect them.
