Hello! If you're looking for a study guide for your AP Statistics or Elementary Statistics students, this is a great resource! It's an info sheet of all the common sampling methods, along with the steps for how to conduct each sampling method. It also includes information on what type of sampling biases arise, and whether each sampling method collects data that has high or low bias. It serves well as a review guide before a chapter test, the AP Statistics exam, or just as a general lesson overview. I like to print these for my students so they can use it to study or follow along with me as we go over the lesson on sampling.
