The range is a measure of what aspect of a dataset?

• A. central tendency.
• B. shape of distribution.
• C. standard deviation.
• D. dispersion.

Answer: (D)

The range measures how spread out the data are, capturing the overall extent from the smallest to the largest value. It’s calculated as the maximum minus the minimum, giving a quick sense of how far apart the extreme values lie. Because it relies only on those two end points, it’s a simple, crude measure of dispersion and can be heavily affected by outliers, while ignoring how the rest of the data are distributed. It doesn’t tell you about the central tendency, which would be a typical value like the mean or median, nor does it describe the shape of the distribution (such as skewness or how data cluster). Other dispersion measures, like standard deviation, use all data points to give a more nuanced sense of variability, but the range specifically reflects the spread between the extreme values.
