Mаrketing Reseаrch Club cоnducted а study tо investigate hоw consumers value different features of GPS. From some preliminary analysis, they concluded that four attributes contributed the most to the attractiveness of a GPS. They are: Accuracy (measured by number of feet a GPS is able to locate you), Price (in dollars), Display (black and white vs. color), and Battery Life. They used the following factors and levels for the study. Accuracy (2 levels): 10 feet, 50 feet Price (2 levels): $150, $250 Display (2 levels): Color, Black and White Battery Life (2 levels): Lasting 32 hours, Lasting 12 hours They measured consumer preference ratings for the 16 (=222*2) product profiles and label the ratings as “utility” in the dataset. The dummy variables are defined as follows: Accuracy = 1 if the GPS is able to locate you in 10 feet, 0 otherwise Price = 1 if the GPS is offered at $150, 0 otherwise Color = 1 if the GPS has Color display, 0 otherwise Battery = 1 if the battery for GPS lasts 32 hours, 0 otherwise They used linear regression to estimate the model.

A retаil chаin stоre is testing three prоmоtion strаtegies for a new store brand soup. A marketing research team helps this client to conduct experiments to examine the relationship between promotion strategies and the sales of the soup. The team selected 15 similar stores to do the experiments. They randomized the 15 stores into three experiment conditions: Experiment condition 1: Five stores were selected to have a display of the new product in front of the store and no flyers were sent. Experiment condition 2: Another five stores were selected to put the display of the new soup in the isle for soups and no flyers were sent. Experiment condition 3: Flyers were sent to the neighborhood of the remaining five stores but no special display was put in the stores. They collected the sales of the new soup in each store. Here is the data they have collected.
