Sometimes I need to subsample a dataset for my analysis/modelling. What are the strategies/things to check for to select a subsample that's representative of the entire sample? And in addition, how to evaluate the 'representativeness' of the subset taken?

I visited this post, but I think its focus is on reducing the volume of the data instead of getting a qualitatively representative sample of the larger set. Besides, I'm asking for non-time series data, which is something more general.

I also visited this post, but find it not that relevant.

It would be nice to hear how things are done in (industrial) practice. TIA.

    $\begingroup$ As mentioned in the first post for non-sequential data, have you tried simply sampling random rows from the dataset? $\endgroup$

  • $\begingroup$ @Oxbowerce, thanks for the recommendation. I've edited the question to reflect what I truly want to ask for, in addition to how to sample, also how to evaluate. Thanks for your inputs :) $\endgroup$
