I'm going to do the sampling distribution of the sample mean, and I'm going to run 10,000 trials. So I'll do one animated trial, just so you remember what's going on. So I'm literally taking first five samples from up here, find their mean. Now I'm taking 25 samples from up here, find its mean, and then plotting it down here. So here the sample size is 25, here it's 5. I'll do it one more time. I take 5, get the mean, plot it.
