Evaluating public policy discussion

You have been contacted by the Office of Continuing Education to design a sampling plan in order to determine reaction to a public service announcement on your college's night courses. The announcement is intended to attract more adults into the evening courses.

Use ONE of the following methods to design a sampling strategy:

• *Design a simple random sample. Identify the population and sample frame. Discuss the adequacy of the sample frame. Give specific directions on how members of the sample would be selected.
• *Design a systematic sample. Identify the population and sample frame. Discuss the adequacy of the sample frame. Recommend a sample size, indicate the skip interval, and how to select the first 10 members of your sample.
• *Design a cluster sample. Identify the population and sample frame. Discuss the adequacy of the sample frame. Give specific directions on how members of the sample would be selected.
