Central Tendency

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.

• Add the two numbers together and divide by 2.

• Pick the one that you want.

• Subtract the two numbers.
