Warm Up
Write a total number of letters in the first and last names of 9
celebrities, historical figures, or people you know. Organize your data
in a table.
I. Objective

II.
 Order the values in your data set from least to greatest. Then
write the data on a strip of grid paper with 9 boxes.
 Now take your strip of grid paper and fold it in half. On what
number is the crease? What do you notice? This value is called the
median.
 How many values are greater than the median? How many are
less than the median?
