Hello, I have a sample of 415 with three dimensios for each and I'm trying to test the means for normality.
-
Shapiro tests do not support normality but I've read that's doubtfull with bigger samples (here it's 415).
-
I'm not sure what to make of the qqplots. They're pretty much on the line, except for the beginning and end on two of the dimensions...
Would appreciate any help.
