Aug 7, 2015 at 16:23 comment added Shamp0o My tutor said not to get hung up on this problem and to just do simulations with a sample of small and big parcels respectively and one with a "representative" sample if I'm able to find one. Hence my original question.
Aug 7, 2015 at 16:23 comment added Shamp0o Thanks for you answer. I'm not sure I understand though. Just to clarify, the optimum shouldn't be found by adjusting parcel parameters. In reality I have no influence on those. But I don't think that's what your suggesting anyway. If I understand correctly you suggest I should look for a sample that makes it easiest to determine my optimal system parameters (which include conveyor speed and geometry settings).
Aug 7, 2015 at 15:37 comment added whuber Thank you for the edit (+1). This adds considerable information to the question, because it indicates you are in an experimental design situation and that you are seeking to estimate a response surface in order to optimize a response. That suggests you might not want a statistically representative sample--instead, you need one that will give you the best possible estimate of the optimum. If you know nothing about the response, you might want your sample to exhibit a variety of extreme characteristics, whereas if you know about where the optimum is, you want the sample to be near it.
Aug 7, 2015 at 14:47 comment added Shamp0o A friend also just suggested clustering to me. I'm not familiar with cluster analysis so I guess I'll have some reading up to do. I edited my question to give some information about the simulation. I hope this helps.

information about the simulation
Aug 7, 2015 at 14:00 comment added gung - Reinstate Monica If you are randomly sampling, the data should be representative (in the ordinary sense of the word), nor could there be any true outliers.
Aug 7, 2015 at 13:52 comment added whuber The practical meaning of "representative" in this instance will have to depend on what you are simulating and the purpose of that simulation. Could you tell us a little about those?
