A representative sample is a group of subjects selected for study that matches the population on important characteristics such as age and sex. This ensures that the sample is comparable to the population and can be used to make accurate generalizations about the population. A focus group is a specific type of qualitative research method that involves a small group of people discussing a particular topic. An experimental group is the group in a study that receives the intervention or treatment being tested, while a control group is the group that does not receive the intervention or treatment and serves as a comparison. Therefore, neither experimental nor control group fit the description of a representative sample.
