Each year, Business Week publishes information and rankings of MBA programs. The data file MBA Analysis contains data on several variables for eight reputable MBA programs. The variables include pre– and post–MBA salary, percentage salary increase, undergraduate GPA, average GMAT score, annual tuition, and expected annual student cost. Compute the mean, median, range, variance, and standard deviation for each of the variables in the database and write a short report that summarizes the data using these measures. Include any appropriate charts or graphs to assist in your report.
