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. WebOn its own, it does not mean much, but it is particularly helpful when you compare two different samples: Sample 1: 1,2,3,4,3,1,2,3. Variance: small Sample 2: 1,2000,-23,500. Variance: much larger 1 comment ( 6 votes) David Spector 9 years ago
