OpenIntro Example: Stent Studies with Quadstat, R and SAS

The OpenIntro Textbook uses the stent30 and stent365 datasets. From these datasets the text mentions that the proportion of volunteers with stents who saw a stroke event after a year was larger than the number of volunteers who did not have stent and did not experience a stroke.

We can come to the same conclusion as the textbook using Quadstat. Open up a browser window to load the Contingency Table web application and select the stent30 dataset from the dropdown select box.
