Answer 2

it is tough making sense of your numbers. But you should find the mean (the average) for both classes.

to find the average: add up the numbers, and divide by how many numbers you have.


then find the median It's the "middle number" : put the numbers in order and pick the middle number (of if it's a tie, the average of the two middle numbers)
