regression case study

Bowie State University athletic department wants to develop its budget for the coming year, using a forecast for football attendance. Football attendance accounts for the largest portion of the University revenues. The new President of the university who is also a football fan has asked the athletic director to come up with strategies in promoting the university football team. The athletic director believes that attendance is directly related to the number of wins by the team. Instead of attempting to predict attendance based on only one variable (wins), the athletic department has included a second variable for advertising and promotional expenditures as well. The university president is anxious to know the result of this forecast to determine strategies that improve attendance and boost revenues for the University. The business manager of the BSU football team has accumulated total annual attendance figures for the past 8 years:

Wins

$14500

21300

32500

Given the number of returning starters and the strength of the schedule, the athletic director believes the team will win at least seven games next year. He wants to develop a multiple regression equation for these data to forecast attendance for this level of success.

Discussion questions

  • Given that Attendance as the dependent variable and Wins and Promotion as independent variables, use excel to estimate the relationship between attendance and promotion and wins. (Copy and paste results from excel output). Also write down the estimated equation.
  • What is the strength of this relationship? Use the coefficient of determination R squared from the excel output to describe this relationship.
  • Is the relationship significant? Use the “Fisher significance” from the excel output to determine this. Begin by stating the null and the alternate hypotheses.
