Which data set is the most spread from its mean?

Answer

Explanation

Each data set has a mean of 22. Compare how far the values are from 22 by adding their squared deviations: A has 472, B has 198, C has 1,094, and D has 136. Since C has the largest total squared deviation, its values are most spread from their mean.
