<h3>What is
Cross-sectional research?</h3>
A cross-sectional study is a form of observational study in medical research, social science, and biology that analyzes data from a population, or a representative subset, at a specific point in time—that is, cross-sectional data.
Cross-sectional studies are used to analyze a population's illness burden or health requirements, and they are especially effective in informing health resource planning and allocation. A cross-sectional survey can be used to measure the burden of a certain disease in a defined population.
Cross-sectional studies capture a single point in time, gathering data from a research group at a particular point. This is often done with a single survey, questionnaire, or observation.
