What might influence the results of participant observation?

Participant observation is a qualitative research method where the researcher immerses themselves in the setting they are studying, often interacting with the participants to gain a deeper understanding of their behaviors and perspectives. The engagement of the researcher in the environment can significantly influence the results. When a researcher becomes actively involved, their presence and actions might affect the dynamics of the group being studied, which can lead to biased observations or altered behaviors from the participants. This interaction can change the way participants behave, known as the Hawthorne effect, where individuals modify their behavior in response to being observed.

Thus, the researcher's engagement is a critical factor in how data is collected and interpreted. Influencing factors such as these are key considerations in qualitative research, highlighting the importance of reflexivity—the awareness of how one's involvement with the research setting can shape the findings.

In contrast, random sampling, blind study designs, and the sample size are more relevant to quantitative research methods aimed at reducing bias and ensuring generalizability, but they do not directly impact the qualitative insights gleaned from participant observation in the same way.
