Question

Given the set of numbers $\{4,5,5,6,7,8,21\}$, how much higher is the mean than the median?

• A. $2$
• B. $4$
• C. $8$
• D. $5$

Answer 1

Answer: (A)

$2$

Given set is $\{4,5,5,6,7,8,21\}$

The mean of the set is the sum of the numbers divided by the number of terms: $56+7=8$.

The median is the middle number: $6$.

Therefore, the mean to the median, $8$, is $2$ greater than $6$.
