manifest observational study

A manifest observational study is a type of research where scientists observe and record real-world behaviors or outcomes without intervening or changing anything. They simply watch and gather data on what naturally occurs, such as how people use a new product or how a disease spreads. These studies help identify patterns and relationships in everyday settings, providing valuable insights without manipulating variables. Because they reflect real life, findings can be more applicable to general populations, although they can't definitively prove cause-and-effect relationships.
