If the data are very close to each other, then there is low variability. If the data are very spread out, then there is high variability. How do you measure variability? It would be good to have a number that measures it. This section will describe some of the different measures of variability, also known as variation.

We shall discuss some of the most common measures: range, interquartile range, mean absolute deviation, variance, and standard deviation.
