I have the take the West E test in Elementary Education in a few weeks. I started studying and some of the questions I can’t quite remember and some I have no clue. One question asks about finding the range of a set of numbers. It’s been years since I’ve done anything with range or mean, median or mode. So I searched online for definitions. The most helpful one is actually a rap.

The MMMR Rap

The M, The M, The MMMR Rap.
The M, The M, The MMMR Rap.

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 eyes-
you'll only have one # to your surprise.

Last but not least is our friend the Range-
He 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'!

The M, The M, The MMMR Rap.
The M, The M, The MMMR Rap.
When you sing it out loud--it's all just a snap!

Thank you to whatever teacher came up with this because it helped me remember.
