The median is 12.6.
Explanation:
To find the median you list them from greatest to least then whatever number is in the middle is your median.
11.8, 11.9, 11.9, 12.2, 12.3, 12.9, 13.3, 13.4, 13.6, 13.7
So the middle two numbers are 12.9 and 12.3 so you would find the average by adding them together and dividing by 2.
12.3+12.9=25.2
25.2/2=12.6
