Guttman reliability spss

Guttman 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. WebJul 10, 2015 · Informasi Tambahan dalam Uji Reliabilitas Alpha Cronbach’s dengan SPSS.
