Explanation:

1. In sociology, experiments often face ethical issues and may lack realism as they are artificial settings. They can test cause - and - effect, can be replicated, and are not necessarily less reliable than surveys.
2. In sociological research, a variable is a characteristic that can change or vary, not an ethical principle, a research method, or a fixed number.
3. Confidentiality in research protects participants' private information, not eliminates bias, presents consent, or ensures data is accurate.

Answer:

1. They often lack realism and raise ethical issues
2. A characteristic that can change or vary
3. It protects participants' private information
