A sociologist begins participant observation of a group of community college students in the hopes that she can learn more about how young people form new relationships. When the sociologist is asked to teach an ethnography class, she hangs out with many of those same students and teaches them more about ethnography in a small group setting. She quickly begins to see many of the group members as her friends, and participates in social events with them. Identify the aspects of research methodology that might be problematic for this study.
