I would go with biased sampling. I am not sure what "experimental sampling" is supposed to be exactly.

In biased sampling though, there is an "unequal" (more like unfair) selection procedure that favours some units over others.

In simple random sampling, all the units have an equal probability of selection.

In representative sampling, this one is a bit tricky because there are different methods to get a representative sample, although it's not supposed to be too biased. It's possible that you may disregard some individuals from the sample because they're not "representative", but overall I would say "biased sampling" would have a much stronger effect.
