Given the data 21, 13, 13, 37, 13, 23, 25, 15:
A. What is the outlier in the data?

Not looking for answers, just need a demonstration on how to find the outliers, I can't figure it out.
Answered by Damon
Make a graph and look at which one seems kind of nutty. Like 37 is sort of bigger than the others

I did, and I somehow still got lost. I wish I could figure this out. I'm assuming 37 and 21 since those are really my only options, but I want to be able to prove it.

Surely not 21, since 25 is between 21 and 37.
Find the mean, and note that 37 is way farther from the mean than the other numbers.
