Hello there!
First, we need to put our data set into proper numerical order (least to greatest).
Set: , 1,2,2,4,4,5,6,7,8,9,11
Now, to find the mean, we need to add them all up.
1 + 2 + 2 + 4 + 4 + 5 + 6 + 7 + 8 + 9 + 11 = 59
Then, divide it by how many numbers there are : 12
59 divided by 12 = 4.9166667
Round it to the nearest tenth.
4.9166667 = 4.9
This means the average number of runs scored per game is 4.9 runs.
