Step-by- step explanation:

Mean: The "average" number; found by adding all data points and dividing by the number of data points.

Add up all numbers: 12+15+3+13+9+6+11=69

Divide the sum by 7 because there are 7 numbers in total:

69/7= 9.85714285714

Round to nearest 10th 9.85714285714= 9.9

Median: The middle number; found by ordering all data points and picking out the one in the middle (or if there are two middle numbers, taking the mean of those two numbers)

So 12,15,3,13,9,6,11. Cross out 12, 11, 15, 6, 3, 9 then 13 will be left so the Median is 13
