Know what mean and median are?

anonymous · Answer

yes the mean is when you add the data up n divide it by how many numbers there are and the median is the middle number

e.mccormick · Answer

OK.  Now, if you look at that line, it is a curve.  Does it have more low end values or more high?

anonymous · Answer

high?

e.mccormick · Answer

I think so... The scale is what does it.  If it was on a 1:1 scale, it would be low.  But because it is 1:3  as in 1 inpot to 3 output, it is actually going up pretty quick.

anonymous · Answer

ok but I still don't understand the question

e.mccormick · Answer

The thing that gets me is that it is concave, curved down, so it does stay low for a while before shooting up.

e.mccormick · Answer

Ah, yah.  If you draw in a median line, then look at it.  Try that on the real graphic.  Is there more above the median or below?  Because that will shift the average.
