Introducing our latest Rx Bricks Collection: Biostatistics, Study Design, and Epidemiology

Biostatistics, Study Design, and Epidemiology

This week, we released a new Rx Bricks collection on Biostatistics, Study Design, and Epidemiology. Biostats is an area where medical students aren’t always comfortable, since, unlike anatomy, physiology, and pathology, it deals with areas that heavily involve math and statistics.

However, biostatistics and epidemiology serve as the foundation of evidence-based medicine, and are considered key competencies among practicing physicians. In the era of Covid, these skillsets have become even more critical, whether modeling for the spread of an epidemic or determining the probability of developing effective vaccines.

In this collection, we provide an introduction to the principles and practice of biostatistics, study design, and epidemiology, framed through the lens of public health. The goal is to prepare medical students so that they can be ready to answer questions like:

  • Who is impacted by a particular health problem?
  • How prevalent is it?
  • What is causing the issue?
  • Are there ways it can be treated and/or prevented?

Here is a look at what we cover in this new collection, from the fundamentals of statistics to the basics of study design to the basics of epidemiology.
