An observational study involves observing and recording data without any direct interaction or intervention with the human subjects under study. It is a non-experimental research design that can be used to collect data on natural behavior, attitudes, and perceptions. In contrast, experimental research involves manipulating variables and testing hypotheses by creating a controlled environment with human subjects. Normative surveys and longitudinal research may involve contact with human subjects and are not necessarily non-invasive.
