Dear all,
I have a question concerning normal distribution and normal plots. I
have a=
sample of 250 subjects with some psychological scores that are not
normall=
y distributed. With scaled score conversion and cumulative distribution
fun=
ction I tried to approximate the distribution to normal distribution.
Howev=
er, kolmogorov-smirnov test is still significant which refutes the
normalit=
y. Q-Q plots on the other hand show promising results for scaled
scores. Do=
es my data considered normally distributed in this case? My goal is to
use =
these scores in discriminant analysis which presumes the data has a
multiva=
riate normal distribution.=20
All the best,
Arman
