Problem
A critical first step in data mining is to perform initial exploratory data analysis. You have collected a data set of customers coming to your store in Back Bay Boston. Specifically, you have data on the dollar amount customers spent, about 2,000 shopping instances, as well as data from the weather service for each day. What graphical technique could you use to compare the distribution of spending patterns across customer who shop in your store on rainy days compared to sunny days? Explain what this visualization would look like. Make sure your method allows for easy comparison of the central tendency (mean or median) of the distribution.
