Now Mode, Mode, I've been told,
is the # that you see the most.
Median, Median, Median, is the man.
The man in the middle, the man in the middle.
Just line up the #'s the best you can
From smallest to largest,
From smallest to largest.
Now Mean, Mean, he is the best.
Of course he is better than all the rest.
Just add, add, add all your #'s,
and when you divide
you won't believe your eyesyou'll only have one # to your surprise.
Last but not least is our friend the RangeHe isn't the best, but he sure is strange.
You start with the Hiiiggghhhh and subtract
the Loooowwww!!!
You've got the Range and there is no mo'!
