Frequently Asked Questions

Who wrote the ZumaStat programs?

The ZumaStat programs were written by James Jaccard who is currently a Professor at the Florida International University in Miami.  Dr. Jaccard is a member of the American Statistical Association and has written numerous journal articles and books on statistical methods, both introductory and advanced. 

Does ZumaStat work with SPSS if SPSS is accessed through a server?

The SPSS interface portion of ZumaStat (i.e., Z Plus) was designed to run with stand-alone PC versions of SPSS in a Windows environment.  It will work in some server environments but not others.  If you use SPSS on a server, contact us through our tech support e mail and we will help you determine if your server set-up is compatible with Z Plus.  The Means, Frequencies and Correlation packages of ZumaStat all can  be used outside of the SPSS environment as stand-alones, if need be.
