WebbMean 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. WebbThe standard deviation is calculated using the "n-1" method. Arguments can either be numbers or names, arrays, or references that contain numbers. Logical values and text representations of numbers that you type directly into the list of arguments are counted.
