Means VS all trials

[adenton2]

Hello,

I am using ex1d_anova_2onerm.m and noticed I get different F-statistics depending on whether I use the means (i.e., F = 11.01) compared to all trials (i.e., F = 10.47). I thought this was strange because a comment found on post #56 explains, "For balanced designs the same F statistic will be produced regardless of whether you use means or all trials."

Here is an outline of my data set:

SUBJ = 18 participants
A = 2 conditions
B = 2 conditions (repeated measures)

Three measures for each condition are included when analyzing all trials. Both designs are balanced.

Thank you.

Hello, I'm so sorry for the delay!

Can you please copy-and-paste a script that calculates the F-value in these two different ways?
