WebThe distribution of all of these sample means is the sampling distribution of the sample mean. We can find the sampling distribution of any sample statistic that would estimate a certain population parameter of interest. In this Lesson, we will focus on the sampling distributions for the sample mean, \(\bar{x}\), and the sample proportion ... WebA sampling distribution is a probability distribution of a certain statistic based on many random samples from a single population. This calculator finds the probability of obtaining a certain value for a sample mean, based on a population mean, population standard deviation, and sample size.
WebThe distribution of these means, or averages, is called the "sampling distribution of the sample mean". This distribution is normal N ( μ , σ 2 / n ) {\displaystyle {\mathcal {N}}(\mu ,\sigma ^{2}/n)} ( n is the sample size) since the underlying population is normal, although sampling distributions may also often be close to normal even when ...
