Interpretation of a graph please ?

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.

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.
