WebMean is like finding a point that is closest to all. But it gets skewed. If for a distribution,if mean is bad then so is SD, obvio. Standard deviation is how many points deviate from the mean. For two datasets, the one with a bigger range is more likely to be the more dispersed one. IQR is like focusing on the middle portion of sorted data. WebConsequently, if we know the mean and standard deviation of a set of observations, we can obtain some useful information by simple arithmetic. By putting one, two, or three standard deviations above and below the mean we can estimate the ranges that would be expected to include about 68%, 95%, and 99.7% of the observations.
