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.
