If the wrong movie is shown, it could reduce event turnout by 50%. I would like to maximize the number of students who attend and would like to select a PG-rated movie based on the overall student population's movie preferences. Each student is assigned a classroom with other students in their grade. I have a spreadsheet that lists the names of each student, their classroom, and their grade. I know a simple random sample would provide a good representation of the population of students at their high school, but wonder if a different method would be better.

address the following:

• describe a time when you used data in a personal or professional decision. This could be anything from analyzing sales data on the job to making an informed purchasing decision about a home or car.
• Describe how to take a sample of the student population that would not represent the population well.
• Describe how to take a sample of the student population that would represent the population well.
• describe the relationship of a sample to a population and classify your two samples as random, systematic, cluster, stratified, or convenience.
