observational data

Observational data refers to information collected by watching and recording behaviors, events, or phenomena without altering the environment. This type of data is often gathered in natural settings, allowing researchers to gain insights into how things occur in real life. For example, scientists might observe animal behavior in the wild or monitor traffic patterns at a busy intersection. Unlike experimental data, which involves controlled experiments, observational data reflects the actual conditions and actions as they happen, providing valuable context and understanding for various fields such as healthcare, sociology, and environmental studies.
