FAQs

What is the main characteristic of an "observational study"?

The key feature of an "observational study" is that researchers observe and measure characteristics of a population without intervening or manipulating any variables. This contrasts with experimental studies where interventions are applied.

How does an "observational study" differ from a clinical trial?
