Normal distribution - Stata version 13.

[Thomas Rasmussen]

Hello I'm working with a dataset that include 69 pilots, it's a intervention project for my master degree.

I need to make sure if my data are normal distribution ore not.

I already tryed to draw my variable by using:

kdensity VARIABLE, normal
histogram VARIABLE, normal by(Randomizering)
qnorm VARIABLE

My issue is that some of my data do not look normal distribution, but I'm not shure how to test it statistically.
I tried to use:

sdtest VARIABLE, by(Randomizering)


But I'm not sure if it's the right method?

I hope someone can help.



Sincerely, Thomas.
