Normality test: missing p value for some variables

#1
Hi!

I am trying to run normality test for 3 variables and I am just getting p value for one of them.

Has someone faced this problem before?

Thank you for the help!

You want to test whether a sample n=2 is sampled from a normally distributed population.
This doesn't work well with a very small sample such as n=9 (nonsignificant results are meaningless,
due to extremely low power of the test), but with only n=2 it simply makes no sense, I'm afraid.

With kind regards

Thank you for the fast answer.
So in this case I shouldn't check normality at all? And does it make sense to run parametric or non-parametric tests?

I suppose that you have very small sample sizes. In that case, nonparametric tests would often make sense.
But I don't know anaything about your study (research question, sampling procedures, variables and
their measurements, or why you have several sample sizes), so I cannot really answer your question.

With kind regards
