Numerical data in epidemiology is collected through a variety of methods, including:
- Surveillance Systems: Continuous, systematic collection, analysis, and interpretation of health data. - Surveys: Samples of the population are questioned to gather data on health behaviors, conditions, and outcomes. - Clinical Trials: Controlled experiments to test the efficacy and safety of medical interventions. - Observational Studies: Studies where the researcher observes and records information without intervening.
