Answer 8

twisted -- do you know what the words "median" , "mode" and "mean" ... mean? :)
Serious question. without knowing what these words mean, it's next to impossible to solve this problem. (same for many other problems in other subjects...)

Is it the vocab words that are giving you trouble or the actual act of adding up and dividing numbers?

Answer 9

Completely agree mathteacher - my problem with this when I learned it was regarding the terms - not the mathematics behind it. Mean I got, but I had a hard time remembering median vs. mode. What about you @twisted?

Answer 10

i know what they mean but am constently getting them all confused

Answer 11

I hear you - try breaking them up mentally in a different way. Mean = average. Median = middle. And mode = more. That's how I did it at least, see what works for you.

Answer 12

thanks for the tip

Answer 13

You're welcome. Oh, and happy New Years ;)

Answer 14

How I remember them:

The AVERAGE teacher is "mean". :)
The "median" is that line in the MIDDLE of the road.
Mode = The one that appears the most.
