Answer 8

Yeah someone else help us with median

Answer 9

@tcarroll010 could you help me

Answer 10

If you have an odd number of data points, the median is the middle one, after writing them out from lowest to highest. If you have an even number of data points, you average the middle two data points.

Answer 11

So, in this case, you have 12 data points.

Answer 12

so you write them highest to lowest based on the amount of x's?

Answer 13

data points number 6 and 7 are valued as 15 and 15. You wthem, but in this case, it's clear that the average is 15. So, that's the median.

Answer 14

so all my answer is, is 15?

Answer 15

Yes, you would start wring them as 12, 13, 14, 14, 15, 15, 15 and so on. Yes, in this case both the mean and median are the same.
