If the highest score in a distribution is 24 and the lowest score is 15, what is the calculated range?

To calculate the range of a distribution, subtract the lowest score from the highest score. For example, if the highest score in a dataset is $$24$$ and the lowest score is $$15$$, the range is calculated as $$24 - 15 = 9$$.

The range is a straightforward measure of variability calculated as the difference between the highest and lowest scores in a distribution.

Although the range is easy to compute, it can provide a misleading impression of a distribution's variability when outliers are present. Because the range relies solely on the absolute highest and lowest values, a single extreme score will drastically inflate the range, giving the false appearance that the entire dataset is widely spread out.
