Spread; A complement to the center of a distribution is the variation, variability, or spread of the data. In some data sets, the values are concentrated closely, while in others the are more spread out. Some rough measures of spread we have already seen are the range and IQR. The most common measure of spread is the standard deviation.

A measure of spread (variability, dispersion, scatter) refers to how the data within the set is "spread out" (or "dispersed", or "scattered") about the mean. If the data is clustered around the center value, the "spread" is small. The further the distances of the data values from the center value, the greater the "spread". Measures of Spread
