Statistical Biases

by Raywat Deonandan, PhD

Bias is defined as the systematic tendency to magnify or reduce the significance of a particular group or outcome in the analysis of a data set. In clinical research, bias can be a manifestation of different variables, including technical factors (e.g., poor study design) and personal prejudices that skew inclusion/exclusion criteria.

In this course, the student will be introduced to the different types of bias and how these are manifested in clinical research.

For optimal understanding, the student is required to have preliminary knowledge of epidemiology. Since some concepts may be very abstract to some, it’s encouraged to rewatch some video lectures until the concepts are fully grasped.

Overall an excellent course
By Jeff B. on 09. February 2022 for Statistical Biases

The only criticism I have is that my preference would be for longer and fewer videos. I know that many students today prefer the shorter format, but as someone who is older, that's not my preference. Otherwise, the teaching has been clear and concise.
