## Re: Statistical Significance Testing Versus Total in CTABLES - Forgot to Mention Something

 The rows can be proportions or they can be means.  Let's say a mean example is the number of children in each household and we wish to test if there are statistically significant differences among the regions.  A proportion example could be who people are likely voting for in the next presidential election.  Again, would be interesting to statistically test the proportion that would choose Hillary Clinton among the four regions. But the part that I really should clarify is what I mean when I say I want to test the columns by Total.  When I wish to test North versus Total I mean North versus Total minus North, or North versus all the other regions.  That's what the test within a platform like CfMC does. Thank you and sorry about any of the confusion.  Still hoping there is an automatic way to do this with SPSS.

Just what is it that you're trying to test? "Testing columns versus Total" is pushing numbers around. What do you mean? So, you have four regions. Do you mean the regions are your "columns"? What, then, are your rows? Are they alternative values of another categorical variable? In other words, you have not given us enough information to answer your question.
