Can be derived from the sampling distribution
WebAug 20, 2015 · Because of the Central Limit Theorem, the mean of the sampling distribution would also be 110g. However, because the population mean is 100g, the sampling distribution of the sample mean will have a mean of 100g. So the only reason why we create the theoretical sampling distribution is so we can "capture" the … WebOct 8, 2024 · In this situation, the mean will vary from sample to sample and form a distribution of sample means. Statisticians refer to this type of distribution as a sampling distribution. Sampling distributions are crucial because they place the value of your sample statistic into the broader context of many other possible values.
