Which is a measure of variability in descriptive statistics?

Explanation:
Variability is about how spread out the data are. The standard deviation quantifies that spread by measuring how far each value tends to be from the mean. A small standard deviation means observations cluster near the mean; a large one indicates wide dispersion. The mean, median, and mode describe central position, not how spread out the data are, so they don’t measure variability.
