Kuder-Richardson 20 (KR20) scale reliability calculation?

[Wesley Joe]

Can SPSS calculate the KR20 reliability figure for assessing scales that are composed of dichotomous items?  Thanks.

[Anthony Babinec]

KR20 is a special computational case of cronbach’s alpha.

So, you can get what you need from the RELIABILITY procedure.

On the menu: analyze -> scale -> reliability analysis.
