Two More M's and an R

Two More M's (and an R)

You've heard about the 4 M's...

Mean, median, mode, and MAD.

There are two more "M's" in statistics.

• Minimum

• Maximum

The minimum:

The smallest value in a data set.

The maximum:

The largest value in a data set.

There's also an "R".

• The "r" stands for "range".

• The range is the distance between the minimum and the maximum.

• Range is another way to measure how spread out a data set is.

• A large range means the data is more spread out. A small range means it is more clustered together.
