I'm trying to do the non-parametric test for 2 factor mixed anova.
I got 2 factors, one is within-subject factor, AGE(2levels), and the other is between-subject factor, Speed(6levels).
One dependent variables, RT.
The data, I got, is not satisfied with the normality and homogeneity of variance.
So I tried to do the non-parametric test and use the Friedmann test function(friedman.test) in R .
and I got the error message as below..
"Error in friedman.test.default(RT, Speed, AGE) :
friedman.test error: not an unreplicated complete block design"
How can I deal with this problem?
