# MA215 Grantham University Week 2 ROI Excel Spreadheet Project

Project Week 2

For these project assignments throughout the course you will need to reference the data in the ROI Excel spreadheet. Download it here.Remember the Central Question: Which major, business or engineering, will give the better ROI? For each of the 2 majors calculate the mean, median, minimum, maximum, range, and standard deviation for the columns â€˜Costâ€™ and â€™30-Year ROIâ€™. Define each of the terms in #1, and explain how each can be used to provide information as it relates to the central question.By hand or with Excel, for each of the 2 majors calculate the probability that a college picked from the column for â€˜School Typeâ€™ is â€˜Privateâ€™.By hand or with Excel, for each of the 2 majors find the probability that a college with the â€˜School Typeâ€™ â€˜Privateâ€™ has a â€™30-Year ROIâ€™ between \$1,500,000 and \$1,800,000.This is your highlighted box for your project: Use the definitions and explanations in #2 to analyze the data. Compare the data for the means, ranges, standard deviations etc. and discuss how these comparisons help answer the question of which major will have a better ROI? What does it mean if there is a greater range in terms of ROI? What does it mean if there is a greater standard deviation in terms of ROI? Which major is looking like it has the better ROI right now? Why?

Hint from Dr. Klotz: Don’t skimp on the analysis. Statistics is more than crunching programs – we have to know what the data set is telling us.
