In this free online video program, students will learn that "causation is only one of many possible explanations for an observed association. This program defines the concepts of common response and confounding, explains the use of two-way tables of percents to calculate marginal distribution, uses a segmented bar to show how to visually compare sets of conditional distributions, and presents a case of Simpson’s Paradox. The relationship between smoking and lung cancer provides a clear example." This individual video is accessed by scrolling down to the "Individual Program Descriptions - 11.
