Getting normal distributed subset from a normal distributed data set

[Elisa Pieri]

Hello,

I'm sorry if this question is pretty trivial, but I couldn't find a
solution online (maybe it's because I'm not asking in the right way).

I have a data set of N values that follow a normal distribution. I would
like to sample this data set, creating a subset of N/10 values following as
well the normal distribution. How to do that in PSPP?

(I'm using PSPP 0.10.2 on Mint 18.3.)

Thank you!
Elisa

I don't know if this answers your question (because I don't know how to
sample and ensure a particular distribution of the subsample) but any
random sample of a normal population should approximate normality as the
sample size grows, so you could take a random sample:
