This little site contains unlimited amount of problems. The case study name, type of variables, all the data, all the topics this problem applies to, as well as complete answers. The categories range from sports, to health, to education, to economics, to so many others that I have been spending hours looking at this site yet I have many hours of exploration left. When you get to the site, go straight to the box that says: "story problems", that is them. Have fun!!
