Standard deviation measures how spread out the salaries are; a smaller standard deviation means less spread. Shenika’s standard deviation is $7.67, which is smaller than Clarissa’s $12.53, so Shenika’s monthly salary is less spread out. The other statements compare salaries whose standard deviations show the opposite relationship.
