Exam 13: Relationships Between Variables

You are an officer in your college's Student Marketing Association. You are looking for ways to ensure that members will join again the following year. Students tend to join for one semester or one year and then drop out. You decide to take a simple random sample of this year's members and give them a survey. One of the questions asks: "Will you join the SMA next semester?" Yes, No, Don't Know. Another question asks respondents to "check all the following that they feel provides them with 'value' by virtue of being in the SMA:" free food at meetings, getting to socialize in a relaxed setting with fellow classmates, learning about businesses through the guest speaker program, getting job search information through the organization's "Career Search" program, and getting to know your professors on a more personal basis. You want to know which one(s) of these are related to whether or not students will join the SMA in the next semester. What analysis should you run?
