Confounding Variables

May 13, 2024 3 minute read

Confounding variables are a common threat to the validity of research studies. They are variables that are related to both the independent and dependent variables, and can thus make it difficult to determine which variable is actually causing the observed effect. Confounding variables can be difficult to identify, and can lead to misleading results if they are not taken into account.

How to Identify Confounding Variables

Confounding variables are often difficult to identify. However, there are a few things that you can look for, in order to determine whether a confounder may be present.
