Theoretical standard
WebbHow would one go about finding the expected, or theoretical, standard deviation of a population? The problem says there are 1000 data points, all randomly generated between 0 and 20, inclusive. The expected mean is obviously 10, but how would you calculate the standard deviation without actually having the data? Thanks! 1 3 3 comments Best Webb28 sep. 2024 · 2: What is the theoretically expected mean and variance of the sample? Again, the expected sample mean can easily be shown to be the distribution mean. The expected sample variance can be (somewhat more cumbersomely) to be shown to equal σ 2 ( N − 1 N) in which σ 2 is the distribution variance.
