Answer: naturalistic observation
Explanation: Naturalistic observation is a technique used in the study of subjects in their natural habitat without any manipulation or interference from the observer. The aim of naturalistic observation is to describe in detail the behaviour of an organism in their natural setting, situation or habitat.
Conducting a naturalistic observation offers some advantages which include:
I) allowing investigation of behaviours that occur in complex social settings.
II) allowing the researcher to gather qualitative as well as quantitative data and
III) allowing the development of theories based on collected observations etc.
However, it is less useful in studying well-defined hypotheses under precisely specified conditions since they are typically designed not to confirm previously formed hypotheses.
