standard deviation in multi way ANOVA
hello,
i did a multiway ANOVA using 4 crossed factors . JMP shows a significant difference but i noticed that within a factor the standard deviation is exactly the same for all the variables
i guess there must be something wrong but i don't know what i did wrong?
would someone have any idea of what could cause that? or maybe some one knows how the standard deviation is calculated in the multiway ANOV...
