Interpretation of a graph please ?

[Waliyya]

Hi everyone,

You will see in the attached file, a set of command I used with the aim to check for normality of the data. However, I don't know how to interpret the graph obtained. Can you help me please?

Happy new year !

Thanking you in advance.

Have you tried running it through proc npar1way with normality tests?

Take a look at: SAS/QC(R) 9.3 User's Guide

Or check proc univariate normal ;

Graphic shows that long tails at both ends of the data distribution .Which means it is a skewed distribution, such as the lognormal is more appropriate than the normal distribution.
