Method
  • Have students take their data sheets home over the week-end and choose four different t.v., shows at four different times of the day, to collect data for.
  • After they collect the data, have them calculate for each show the percentage of time that was allocated for commercials and the percentage of time that was allocated for the show itself.
  • Discuss the findings: do the t.v. shows allocate the same ammount of time for commercials?, which t.v. shows had more commercials?, why could this be so?
