Business Statistics: Chi-square Test
Use the Student_Data.xls file which consists of 200 MBA students at Whatsamattu U. The file includes variables regarding students` age, gender, major, GPA, Bachelors GPA, course load, English speaking status, family, weekly hours spent studying. Each of the three assigned problems should be formatted as a one page memo. Answers to all three of the problems should be submitted via the Drop Box as a single Word document with each of the problems clearly labeled. Be sure to include your name on the document itself!
COMPLETE PROBLEM 1: Historically, in the MBA program at Whatsamattu U., about 40% of the students choose a Leadership major, 30% choose Finance, 20% choose Marketing, and 10% choose no major. Does the most recent class of 200 MBA students fit that same pattern or has there been a shift in the choice of majors. Using the sample of 200 students (in the data file), conduct a Chi Square Goodness of Fit test to determine if the current distribution fits the historical pattern. Use a .05 significance level. Report on your findings (100+ words, 3 or more sentences). In your report, be sure to include the tables with the results of the Chi-square test as well as a chart (a bar chart or column chart) comparing the expected vs. the observed frequencies.
COMPLETE PROBLEM 2: While job opportunities for men and women are considerably more balanced than they were 40 years ago, the career aspirations may still differ. Is there a difference in majors chosen by men and women? Using the sample of 200 MBA students (in the data file), conduct a Chi Square Test of Independence to determine if one`s choice of major is independent of their gender. Use a .05 significance level. Report on your findings (100+ words, 3 or more sentences). In your report, be sure to include the tables with the results of the Chi-square test as well as a chart (a stacked column chart works well) comparing the expected vs. the observed frequencies.
COMPLETE PROBLEM 3: You wonder if there is a relationship between students` employment status and their choice of major. Do unemployed students choose majors that have the greatest employment potential? Do fully employed students choose the `easiest` major? Using the sample of 200 MBA students (in the data file), conduct a Chi Square Test of Independence to determine if one`s choice of major is independent of their employment status. Use a .05 significance level. Report on your findings (100+ words, 3 or more sentences). In your report, be sure to include the tables with the results of the Chi-square test as well as a chart (a stacked column chart works well) comparing the expected vs. the observed frequencies.
