Here we talk of the range of a function, as the set of values the function can take on. For highly skewed distributions, the mean can be pulled so far in the direction of the skew that it is no longer a good measure of the central tendency of that distribution. Each horizontal axis is labelled X and has values from 1 to 20, and each vertical axis is labelled Frequency and has values from 1 to 20. The range is the difference between the highest and lowest scores, and the standard deviation is roughly the average amount by which the scores differ from the mean.
