The purpose of this study is to determine whether men or women spend more on average per trip to the grocery store. The study was conducted at Marc's Great Northern grocery store, over several weekends, with the underlying assumption that the results of this study could be extrapolated to at least other grocery stores in the Northeast Ohio area. The data was recorded at the Point of Sale, before coupons were applied to eliminate that factor as a possible confounding variable. I also did not collect any data from the Express (12 items or less) Checkout, because it would decrease the means for both populations, causing them to converge significantly, which would ruin the study. I concluded gathering data when I had reached 120 points of data for women, and a dramatically smaller 40 points of data for men. Regardless of total spending at Marc's, it is evident that women are more likely to go grocery shopping. I concluded based on a Two Sample T-Test that there is no significant difference between the average amount spent per trip to Marc's between men and women.
