...Descriptive Statistics Introduction This week’s team assignment is to collect the team member’s descriptive statistics for week four incorporating the best elements into one team data analysis paper, including data and charts. Descriptive Statistics The research topic for this paper is “McDonald’s is Closing Hundreds of Stores.” As part of the research a sample size of 400 was selected to ensure accuracy of results based on the population size of 410. The given sample size was randomly surveyed to test the variables – Independent Variable - Change in consumer food preference and competitive market place and Dependent Variable – Reduced sales hence reduced profit. Age Three Hundred and Eighty-Five McDonald’s consumers were randomly selected and their ages measured. The age ranges were 15 and 65 years. Average consumer is aged 31 with a standard deviation of 14 years. Approximately half or more of their ages are above 31. Income The income of the randomly surveyed consumers is averaged at $30.82 and with a standard deviation of $14.04. Income range is $15 to $65 and there is enough evidence that half or more of these consumers averages $30.82 per year. Strengths and Weaknesses of Team Members’ Individual Assignments Efforts were made by each team member to better understand the use of the statistical tool made available to us (MegaStat). More knowledge was gained and applied in the interpretation of data and findings on this paper. Additionally, each...

...ork2012 - 2013 Catalog A Message from the President “Sullivan University is truly a unique and student success focused institution.” I have shared that statement with numerous groups and it simply summarizes my basic philosophy of what Sullivan is all about. When I say that Sullivan is “student success focused,” I feel as President that I owe a definition of this statement to all who are considering Sullivan University. First, Sullivan is unique among institutions of higher education with its innovative, career-first curriculum. You can earn a career diploma or certificate in a year or less and then accept employment while still being able to complete your associate, bachelor’s, master’s or doctoral degree by attending during the day, evenings, weekends, or online. Business and industry do not expand or hire new employees only in May or June each year. Yet most institutions of higher education operate on a nine-month school year with almost everyone graduating in May. We remained focused on your success and education, and continue to offer our students the opportunity to begin classes or to graduate four times a year with our flexible, year-round full-time schedule of classes. If you really want to attend a school where your needs (your real needs) come first, consider Sullivan University. I believe we can help you exceed your expectations. Since words cannot fully describe the atmosphere at Sullivan University, please accept my personal invitation to visit and experience...
