Professor Smith is planning to conduct a mail survey of people living in Eugene, Oregon to assess how concerned they are about environmental problems. She needs you to help her select her sample. She has the resources to survey 200 people. First, provide a clear operational statement about the study population – i.e., who qualifies to be included in her sample and how do you identify this study population? How should she select the sample from this population? Which sampling procedure should she use: snowball, quota, or a type of probability sampling? Explain the differences between these types of sampling procedures as they relate to obtaining a representative sample. Write an approximately 300-500 word memo to Professor Smith explaining how you would address each of these issues.
