WebComparing range and interquartile range (IQR) Google Classroom. Range and interquartile range (IQR) both measure the "spread" in a data set. Looking at spread lets us see how much data varies. Range is a quick way to get an idea of spread. It takes longer to find the IQR, but it sometimes gives us more useful information about spread. 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.
