## What's On TV?

Summary: How much time do you spend watching television commercials? In this project your group will focus on the products being adverstised and the amount of time sponsors air their commercials during the programs you watch.

1. Plan It

A. Choose a time. Each group will watch television during a different time of the day.

B. Choose a show. Each member of your group will choose a different program to watch during the group's assigned viewing hour.

• While you view your program, you will need a stopwatch, or a watch with a second hand that can measure the lengths of commercials in seconds.

C. Draw a table. You will need to record your data.

• Create at least 6 two-column tables per viewer in a notebook, similar to the one on page 121 of your textbook, or make copies of the Commercial Break Table here on Education Place.

D. Brainstorm. As a class brainstorm a list of categories for types of commercials. Make sure each member of your group receives a copy of the categories list to use at home.

Our planning completed

2. Put It Together

A. Get permission. Remember to get permission from your parents, then watch your program for one hour.

• Begin recording the commercials at the time your show is scheduled to start in your local television listing.
• Make sure you record information through the closing credits of your program.

B. Watch television. For each commercial break, record the following information in your table:

• The category of each product that is advertised.
• The length of the commercials.

3. Wrap It Up

Share your data. Combine your group's data to complete the Commercials in the Time Slot Tables. Based on your group's data:

• Find the average and median number of commercial breaks in one hour of programming.
• Find the average and median length of a commercial break.
• Find the average and median length of a commercial.

Calculations completed

• Discuss the type of products adverstised on each show. Who do you think the target audience is?
• Do you think television commercials are too long? Explain.
• Will watching television commercials affect your shopping decisions? How?
• Did you calculate the averages and medians correctly?
• Are your data clear and complete?
• Did you work well as a group?
• In what other ways could you organize your group's data?
