Cоnsider the fоllоwing scenаrio: A shoe compаny wаnts to test how effective its new packaging designs are at selling its top 3 shoes. They select the 2 stores with the top sales out of 200 stores across 5 countries and give them each the 3 different shoes below: They record the daily sales data for the packaging at each store for 2 days – store 1 on Monday and store 2 on Friday. The question the company wants to answer is whether there is a significant difference in sales between the three packaging designs. Given the scenario, Discuss the possible flaws in this study design and how you would fix them. Identify and explain the flaws thoroughly. Explain how your changes will fix the flaws. Identify any assumptions you make during your redesign.
