Mean: 11.5
Median: 12


To find the mean, add up every number and then divide that number (92) by the amount of numbers that you have.

To find the median, line up the numbers (include repeats) in order from least to greatest and find the number in the exact middle. If there is no middle number, you can find the middle number between the 2 numbers closest to the middle. If the number is between two repeating digits, then it is that digit.
