I need Help in Marketing research ( 3 Questions ) :
1- A national retail store chain has 1,500 stores dispersed throughout the country. The chain’s management wants to test the relative impact of two different, special in-store promotional displays (x1 and x2) on individual stores’ sales. It also wants to know whether not having any special in-store promotional display is necessarily worse then havingx1 or x2. create and describe an appropriate true experimental design capable of meeting management’s information needs
2-Toys & Games is a toy store located in a shopping mall. Toys & Games ran a major in-store promotion (consisting of special displays and price reductions) during the last quarter (October to December) of each of the past five years. Every year, without fail, its sales in the last quarter were at least 25 percent higher than sales in any of the previous quarters. Thus the store manger is seriously thinking about expanding the in-store promotion to at least one other quarter each year.
- What advice would give the store manager?
