1. Suppose you had a group of 72 people. Of those 72 people, 36 were Republicans, 12 were Libertarian and 24 were Democrats. Now suppose you wanted to take a stratified random sample of 6 individuals where the strata were based on political ideology. Discuss how you would construct this sample and how many individuals from each political ideology would be included in your sample.

1. Suppose you had a group of 72 people. Of those 72 people, 36 were Republicans, 12 were Libertarian and 24 were Democrats. Now suppose you wanted to take a stratified random sample of 6 individuals where the strata were based on political ideology. Discuss how you would construct this sample and how many individuals from each political ideology would be included in your sample. 2. There were a variety of random sampling techniques introduced in this chapter including: systematic, simple, and stratified. How would you determine which random sampling technique is the most appropriate (most effective) for a given situation? Be as specific as possible, identifying what information would lead you to choosing each type of sample. 3. Analyze the graphic below and write a quick reflection on what you believe the graph is communicating. Your reflection should be at least 4 sentences long.
