In the previous topic you discovered that you can use tests of significance to compare proportions between two experimental groups. In this topic you will learn that one can also use confidence intervals to estimate the magnitude of the difference in proportions between the experimental groups. You will also study the application of significance tests and confidence intervals to data obtained from observational studies. While you will find that the reasoning and interpretation of these inference procedures is the sam in every situation, you will be reminded that the design of the study dictates the types of conclusions that one can draw.
