I have three groups with unequal sample sizes; n=5, n=4 and n=10. I would like to perform a one-way ANOVA using the Analysis ToolPak in Excel. But I am worried about the different sample sizes. Excel will run the analysis without any error messages, so I wonder if the function automatically corrects for the different group sizes.
Does anyone know if the one-way ANOVA in Excel corrects for unequal sample sizes?
