Every study has error. Understanding the types of error, how to reduce it, and how to interpret results in balance with this error is a critical skill for any medical professional.

In this module, we will look at random and non-random error (otherwise known as systematic bias), how it affects our results, and what good epidemiologists do to avoid, mitigate, or overcome them.
