Question: The file Zeitlerselectronics contains data on customers who purchased electronic equipment either online or in-store from Zeitler's Department Stores.
a. Create a parallel coordinates plot using XLMiner for these data. Include vertical axes for the customer's age, annual income, and distance from nearest store. Color the lines by the type of purchase made by the customer (online or in-store).
b. How does this parallel coordinates plot compare to the one shown in Problem for clothing purchases. Does the division between online and in-store purchasing habits for customer's buying electronics equipment appear to be the same as for those customers buying clothing?
c. Parallel coordinates plots are very useful for interacting with your data to perform analysis. Filter the parallel coordinates plot in XLMiner so that only customers whose home is more than 40 miles from the nearest store are displayed. What do you learn from the parallel coordinates plot about these customers?
Problem: Zeitler's Department Stores sells its products online and through traditional brick-andmortar stores. The following parallel coordinates plot displays data from a sample of 20 customers who purchased clothing from Zeitler's either online or in-store. The data include variables for the customer's age, annual income, and the distance from the customer's home to the nearest Zeitler's store. According to the parallel coordinates plot, how are online customers differentiated from in-store customers?
