Experimentation is the type of research where the investigator manipulates at least one factor (independent variable) and observes its effect on some behavior or mental process (dependent variable). In contrast, surveys involve collecting data through questionnaires or interviews, case studies involve in-depth examination of a single case or individual, and naturalistic observation involves observing behavior in its natural setting without any manipulation of variables.
