agent0smith · Answer

Looks about right. Just add them all up and divide by how many there is.

agent0smith · Answer

"6, 8, 9, 9, 9.5, 10}." but all these numbers are closer to 10 than 2.5 so you can estimate it's near 10

I used this online calculator at http://easycalculation.com/statistics/mean-median-mode.php It popped out 7.2625.

agent0smith · Answer

2.5, 4.1 are the only two below 5, the rest are all above 5

directrix · Answer

Then, I did the mean of these:  Halfway between 2.5 and 10. That did not bear fruit.

>>> good thinking here: 2.5, 4.1 are the only two below 5, the rest are all above 5

agent0smith · Answer

Halfway between 2.5 and 10

that would be 6.25 exactly so i'm guessing we can ignore that one

agent0smith · Answer

Oh i didn't notice you'd already done that, directrix

directrix · Answer

So, that leaves option B, I suppose.
