Kuder-Richardson Reliability Coefficients (KR20) in SPSS?

#1
Dear all,

I am checking how to do a Kuder-Richardson Reliability Coefficients (KR20) in SPSS. I want to use the KR20 to learn about the internal consistency of items. I use the KR20 instead of the Cronbach’s alpha because my items are noted on a binary scale.

I have been asking around but I did not really find anything.
Hope someone could help me.
Best,

Very true.
You can further confirm this by running the same data choosing split half from the drop down, the output is exactly the same!!
