What is the range?

• The sum of the largest and smallest number

• The number in the middle

• The difference between the largest and smallest number

When you are trying to find the MEDIAN of a set of data and 2 numbers are left in the middle after putting them in order from least to greatest, what do you do?

• List both of the numbers as the Median.
