Document Summary
Factorial designs are commonly employed in marketing research to evaluate the e ectiveness of sales strategies. At one supermarket, two of the factors were price level (regular, reduced, cost to supermarket) and display level (normal display space, normal display space plus end-of-aisle display, twice the normal display space). A 3x3 (a 3-by-3) complete factorial design was employed, where each treatment was applied three times to a particular product at a particular supermarket. The response variable of interest was unit sales for the week. To minimize treatment carryover e ects, each treatment was preceded and followed by a week in which the product was priced at its regular price and was displayed in its normal manner. Identify the factors (e. g. , the explanatory variables of interest), and the response variable in this study. explanatory variable 1: price explanatory variable 2: display response variable: unit sales for 1 week. Identify the treatments (factor-level combinations) in this study.
