WebJan 31, 2024 · Sampling distributions describe the assortment of values for all manner of sample statistics. While the sampling distribution of the mean is the most common type, they can characterize other statistics, such as the median, standard deviation, range, correlation, and test statistics in hypothesis tests. I focus on the mean in this post. Standard deviation is a useful measure of spread fornormal distributions. In normal distributions, data is symmetrically distributed with no skew. Most values cluster around a central region, with values tapering off as they go further away from the center. The standard deviation tells you how spread out from … See more Different formulas are used for calculating standard deviations depending on whether you have collected datafrom a whole population or a sample. See more You can calculate the standard deviation by hand or with the help of our standard deviation calculator below.
