An experimental study involves identifying and controlling/manipulating one or more variables to observe how they influence the variable of interest. This allows for cause-and-effect relationships to be established. Observational studies, on the other hand, simply observe and record data without any manipulation of variables. Categorical studies and variable studies are not commonly used terms in statistics.
