This Unit provides students with meaningful learning experiences for them to appreciate the importance of Statistics in making decisions.
Working in groups, students act as members of a marketing research division of a shampoo company. Their task is to identify and propose in which nighttime television series program they should schedule the commercial of their product. To accomplish this task, each group conducts a simple survey on the television series preference of people in their neighborhood. Knowing the most preferred or the most watched nighttime television series will help each group decide where to schedule the commercial.
In the process of doing this, students learn to develop a simple survey questionnaire, use a particular sampling technique, conduct a survey, organize and process their data using spreadsheet, describe their data using mean, median and mode, and present their proposal in class, supported by the results of their survey.
After the presentations of the proposal of each group, the teacher then discusses further the results of the survey applying some measures of variability that will help describe more accurately the data.

The first version of this Unit Plan was developed by Monalisa Sasing of UP NISMED as part of the Pedagogical Support System for 2005 MTs.
