And let's say in that first sample, I pick a one and let's say I pick a two. Well, then I can calculate the sample statistic here. In this case, it would be the sample mean, which is used to estimate the population mean. And in this, for this sample of two, it's going to be 1.5. Then I can do it again. And let's say I get a one and I get a three. Well, now when I calculate the sample mean, the average of one and three or the mean of one and three is going to be equal to two.
