WebMar 26, 2024 · As a random variable the sample mean has a probability distribution, a mean μ X ¯, and a standard deviation σ X ¯. There are formulas that relate the mean and standard deviation of the sample mean to the mean and standard deviation of the population from which the sample is drawn. In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean (also called the expected value) of the set, while a high standard deviation indicates that the values are spread out over a wider range. fission energy bottle
