Outliers Can Be Important Too

A value that "lies outside" (is much smaller or larger than) most of the other values in a set of data.

For example in the scores 25,29,3,32,85,33,27,28 both 3 and 85 are "outliers".

 

If you plan to go on vacation, you would probably not want to go to the edge of a volcano.  

It's much too hot there.  The mountains have a much cooler breeze.
