Deviation of a and b
Webx ¯ ~ N ( μ x , σ X n). The central limit theorem for sample means says that if you repeatedly draw samples of a given size (such as repeatedly rolling ten dice) and calculate their means, those means tend to follow a normal distribution (the sampling distribution). As sample sizes increase, the distribution of means more closely follows the ... WebThe standard deviation is larger when the data values are more spread out from the mean, exhibiting more variation.
