Unit 1 Contents

In Lesson 2 you learned about the median, another kind of average. You have used the median to average data in labs or other activities. It is the number that is exactly in the middle of the data. For example, to find the median of the number of teachers' pockets, you can list the numbers in order from smallest to largest like this.

• 

Since 3 is exactly in the middle of the data, 3 pockets is the median.

6. Which average, the median or the mode, do you think represents the Teachers' Pockets data better? Tell why.
7. Professor Peabody found the height of six teachers at Bessie Coleman School. He arranged the data in a table. What is the median height for the six teachers? Explain your strategy for finding the median.
