Unit 1 Contents

Luis wanted to watch television after finishing his schoolwork, but his father said, “Not tonight. You watch too much TV.” The next day Luis decided to take a survey of his classmates to find out how much television they watch to see if he really does watch a lot of TV compared to his friends. He recorded his data in a table.

1. What is the median number of television shows watched? Show or tell how you know.
2. What number of television shows is the mode?

1. Did Luis choose a good variable to answer his question? Why or why not?
2. What is another variable Luis could have studied to answer the question? Is your variable categorical or numerical?

4. Based on this data, what can Luis tell his father about how much television he should be able to watch?
