In the first of two videos on basic epidemiology, Professor David Cutler asks, how do we define epidemics and how do we measure them? He defines and differentiates incidence and prevalence and explains how these metrics relate to duration of a disease. Using HIV infection as the illustrative example, he explains how treatment has resulted in a reduction in mortality rates, and therefore an increase in prevalence, despite declining incidence. These basic concepts set the…

VideoMultimedia, Teaching Resource 2018EMR20: Dynamics of an Epidemic
In the second of two videos on basic epidemiology, Professor David Cutler talks about the dynamics of …
In the second of two videos on basic epidemiology, Professor David Cutler talks about the dynamics of an epidemic. He asks, how do we understand when an infection is going to become an epidemic? How can we predict when it will not? He defines an index case and discusses the properties of transmission and people’s interconnectivity, fundamental drivers of epidemics. He uses a visual schematic to differentiate three groups in the population (e.g., susceptible, infected, and removed…

VideoMultimedia, Teaching Resource 2018EMR20: Statistical Analysis, Part 1. Relationship between Two Variables
In this first of three videos on basic statistical analysis, Professor David Cutler discusses the relationship …
In this first of three videos on basic statistical analysis, Professor David Cutler discusses the relationship between two variables using data from a national survey on education and self-reported health. He walks students through the steps of a regression analysis, and the conceptual and mathematical foundation of estimating a regression line. At the conclusion, he reviews the interpretation of the stylized analysis. The second and third videos in this collection, shown below, address how to assess the…

VideoMultimedia, Teaching Resource 2018EMR20: Statistical Analysis, Part 2. Is the Relationship Important?
In the second of three videos on basic statistical analysis, Professor David Cutler, moves beyond …
In the second of three videos on basic statistical analysis, Professor David Cutler, moves beyond summarizing the relationship between two variables to asking if this relationship is "important?" He discussed two dimensions of "importance", the first addressing the substantive question about whether the magnitude of the relationship is meaningful enough or big enough to be important. This second addresses the statistical relationship between the variables and makes up the bulk of the video. In other…

VideoMultimedia, Teaching Resource 2018EMR20: Statistical Analysis, Part 3. Correlation vs. Causation
In the final of three videos on basic statistical analysis, Professor David Cutler, moves beyond …
In the final of three videos on basic statistical analysis, Professor David Cutler, moves beyond asking if the relationship between two variables, health and education, is "statistically significant" to the question about the nature of their relationship. Specifically, he asks what is the difference between correlation and causation, and how is this determined? He explains the importance of identifying other factors that could be influential on the relationship, and demonstrates how one can control for…
