Hello,(adsbygoogle = window.adsbygoogle || []).push({});

I have sample of ~280 measurements. Some are replicates and some are not. I want to remove the measurements that have no replicates, so that I can apply various modeling techniques that need mean/stdev data.

I would like to show that my subsample of ~100 measurements statistically has the same distribution as the whole sample.

What kind of test can I use for this? I believe my difficulty here is that they are not independent groups of data.

Thank you.
