WebMar 26, 2024 · Equation 6.1.2 says that averages computed from samples vary less than individual measurements on the population do, and quantifies the relationship. Example 6.1. 2 The mean and standard deviation of the tax value of all vehicles registered in a certain state are μ = $ 13, 525 and σ = $ 4, 180. WebMay 12, 2024 · Standard deviation is a statistical measurement of the amount a number varies from the average number in a series. A low standard deviation means that the data is very closely related to the average, thus very reliable. A high standard deviation means that there is a large variance between the data and the statistical average, and is not as ... cross stage
