Apsychologist is interested in learning more about how children interact with each other during the school day. the psychologist is particularly interested in discovering the ways in which children behave when they think they are not being watched. what research method would be best used to conduct this type of research? why? what ethical concerns might be an issue in this type of research?

The research method that suits better in this case is the Observational Research Method because it includes ethological studies, case studies, ethnographic studies, etc. The main characteristic of this study is that phenomena are being observed and recorded. It can be problematic if it is not conducted properly. Plainly there is trouble with inner validity. The experiment background can be badly conducted or investigators can be biased. Ethical concerns might be an issue in this type of research but it is important to focus on protecting individuals that  receive the intervention.

it is a better alternative
