At that time, all calculations were done with paper and pencil, and since the formula of

{\displaystyle \lambda _{3}}
was simpler to calculate, he mentioned that

{\displaystyle \lambda _{3}}
was useful under certain conditions. (pp. The their website of reporting only an overall alpha value when an instrument is comprised of several you can try this out scales (as in the Heddy and Sinatra study discussed above) is less useful to readers. If the correlation between variables is 1 the number of correlations is k(k-1)/2 so the formula for the total variance would be So to conclude, if the intercorrelations are zero VLC=k, and if the intercorrelations are 1, VLC=k2Therefore the importance of the covariances within the total variance grows as the intercorrelations between items become higher, and when the number of items gets larger. Guttman’s
