You have done a regression analysis for the catalog sales company you work for, using monthly data for the last year on y = total sales in the month and x = number of catalogs mailed in preceding month. You are asked to prepare a 200-word summary of what regression does under the heading “Regression for Dummies,” to give to fellow employees who have never taken a statistics course. Write the summary, being careful not to use any technical jargon with which the employees may not be familiar.
