Episode Details

This video program stresses the use of caution when making statistical inferences, and features several real life examples to illustrate the need for this caution. Two of these examples will be familiar from earlier lessons: the surveying of park visitors and Glucosamine/Chondroitin Arthritis Intervention Trial (GAIT) example. These segments describe the proper ways to sample; in this lesson, the segments illustrate some of the errors that can be made during statistical inference.
