Assume you are a marketing analyst working for a manufacturer of ready-to-eat cereal. You are given detailed sales data for the past year and asked to create a report showing the differences between the four sales regions (north, south, east, and west) in terms of sales volume, profitability, and changes in sales volume and profitability; marketing expenditures and changes in marketing expenditures; and per capita sales and marketing expenditures.
Q: What type of data is the sales data you are working on? What specific statistical techniques and charts would you use to depict differences, specifically addressing each of the categories constituting your report? Why?
