A measure of dispersion is described as

• A. Measure of dispersion
• B. Measure of central tendency
• C. Mode
• D. Median

Answer: (A)

Dispersion describes how spread out the data are. A measure of dispersion is any statistic that quantifies that spread, with examples like range, variance, standard deviation, and interquartile range. The correct choice fits this idea exactly by naming the category of statistics that capture variability, not center. In contrast, mode and median are specific ways to describe the central location of the data, not how far data values are spread from one another, and a measure of central tendency would describe that central value rather than the spread. So the phrasing that identifies the statistic as a measure of dispersion is the best fit.
