Hello, I've run a 2 way ANOVA of my research results and got these 3 p-values: A=0.001, B=0.069, and A*B=0.167. My professor now wants me to remove the interaction effect from my analysis. Does anyone know how I can do this? In the program I am using (SigmaPlot), there is no option for removing the interaction effect. Also, what exactly would this do to the data and why is it important to remove it? I want to have a clear understanding of this, but I do not know what my professor is asking. He wants me to figure all of this out myself, and I have tried, but I do need help. Thanks in advance.
