i know u?

OpenStudy (anonymous):

I know you too we met before on my account

I would say C

OpenStudy (anonymous):

Finding the Median of data is very helpful when you have an outlier, which in the case of C is 507. Taking the Mean of that would skew the data horribly, and wouldn't be a very accurate measure

OpenStudy (anonymous):

All of the other choices can be summed up more or less with the Mean.

oh ok

I have to choose more them 1

Then A as well. Do you see how most of the numbers are around 9, but the data set also contains a 2? That's an outlier, and would mess up the Mean. So the median is best in that situation also.
