Using SigmaStat to determine significance between specific groups.

Question

I am doing a two way, repeated measures analysis of variance. If the main effects of time and group are significant, but the interaction is not, the program doesn't do a post analysis on individual cells, just an average by the time or groups. If the interaction effect is significant, it does the analysis I need. I need to know how to get it to determine significance between specific groups when the interaction wasn't significant. Can this be done?

Answer 1

Unfortunately, from what it seems, you can determine the significance between specific groups only when interaction is significant. There isn't any tool or option that will allow you to determine it when when interaction isn't significant. I recommend you contact the official developers for further information. Also, you need to know that the SigmaStat has been discontinued and replaced by SigmaPlot.
