Question

What are the mean and median of the following?: 2,5,5,6,6,6,7,7,7,7,9,10

Answer 1

`6.416` and `6.5`

Explanation:

Mean is the average of the numbers. To find the average, you first need to add up all the numbers and divide them by the number of numbers.

`2+5+5+6+6+6+7+7+7+7+9+10=77`

`77/12=6.416`

Median is the number in the middle when you order the numbers in an ascending order. There are two numbers in the middle in this situation, `6` and `7`. So you need to take the average of `6` and `7`

`(6+7)/2=6.5`
