The Distribution of the Sample Mean | |
Summary |
if a random sample of size n is taken from any distribution with a mean of μ and a standard deviation of σ then the distribution of the sample means will have a :
the standard deviation of the sample means is also known as the standard error of the means. if the sample size n is large, say greater than 30, then the distribution of the sample means will be approximately normal. |
