Cross-Sectional Studies

Definition

Cross-sectional studies are observational research methods that analyze data from a population, or a representative subset, at one specific point in time.

Analogy

Imagine cross-sectional studies as taking a snapshot with your camera. You capture everything within your view at one moment but can't see how things change over time.
