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
