Observational Studies are a type of research study in which researchers observe and analyze data without directly influencing or manipulating the variables being studied. Observational studies are widely used in many fields, including medical research, social science, and marketing, to investigate relationships between variables and draw conclusions about real-world phenomena.
Types of Observational Studies
There are two main types of observational studies: cohort studies and cross-sectional studies.
Cohort studies follow a group of individuals over a period of time to observe and analyze changes in their health or other outcomes. Cohort studies are often used to investigate the relationship between exposure to a risk factor and the development of a disease or other health outcome.
