Answer:

Explanation:
Observation is a simple method in carrying out research in which researchers watch what, how and why people do or react. Naturalistic observation is a research method normally psychologists and social scientists use by observing the target audience, especially the natural or spontaneous behavior of participants in natural surroundings. In this method, the researchers just record what they observe.
In this method, the participants may behave naturally, telling their woes and problems so that researchers get the actual and authentic data. Participants may behave differently or indifferently once they are conscious that they are being interviewed or judged. It is highly likely that different sets of researchers may get different results due to their emotional approach to the same problem.
