WebGuttman proposed six measures of reliability that all give lower bounds for the true reliability of the survey. The first is a simple estimate that is the basis for computing some of the other lower bounds. L 3 is a better estimate than L 1, in the sense that it is larger, and is equivalent to Cronbach's alpha.
