Sampling distributions are just like any other distribution, except their "data points" are all possible sample parameters derived from samples of the same size!
A sample parameter is the mean or proportion from a given sample.

Your sample needs to fit certain criteria for the corresponding sampling distribution to be considered normal. (We'll get into this with z-scores vs. t-scores.)
