$6.416$ 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.

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

$\frac{77}{12} = 6.416$

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 $7$

$\frac{6 + 7}{2} = 6.5$

$6.416 , 6.5$
