Now let's think about what happens when we sample. And I'm going to do just a very small sample size just to give us the intuition, but this is true of any sample size. So let's say we have sample size of 3. So there is some possibility when we take our sample size of 3 that we happen to sample it in a way that our sample mean is pretty close to our population mean. So for example, if we sample to that point, that point, and that point, I could imagine our sample mean might actually sit pretty close to our population mean. But there's a distinct possibility that maybe when I take a sample, I sample that, that, and that. And the key idea here is when you take a sample, your sample mean is always going to sit within your sample.
