WebbBecause the sample mean is an unbiased estimator, the sampling distribution is centered at the true average living area of the population, and the spread of the distribution indicates how much variability is induced by sampling only 50 home sales. WebbThe sampling distribution (histogram) of a statistic is the distribution of values taken by the statistic in ALL possible samples of the same size from the same population. The interpretation of a sampling distribution is the same, whether we obtain it by simulation or by the mathematics of probability.

WebbPay attention to the center of a sampling distribution as well as its shape and variability. We teachers understandably devote a lot of attention to the shape and variability of a sampling distribution*. I think we may neglect to emphasize center as much we should. WebbThe discussion on sampling distribution is incomplete without the mention of the central limit theorem, which states that the shape of the distribution will depend on the size of the sample. According to this theorem, the increase in the sample size will reduce the chances of standard error, thereby keeping the distribution normal.
