Final answer:
Ethical research involving human subjects is permissible, and larger sample sizes are preferable for improved reliability and generalizability in social science research.
Step-by-step explanation:
True or false questions pertaining to the methods of conducting social life research, such as experiments on humans and sample sizes in scientific experiments, fall under the category of social studies. In sociology, researchers conduct both lab-based and field research to study human behaviors and social environments.
Contrary to the claim that experiments cannot be done on humans, ethical research on humans is possible and often essential for understanding social dynamics. The key is to adhere to strict ethical guidelines that protect the rights and well-being of participants.
Regarding sample sizes, it is generally true that larger sample sizes provide a more reliable representation of a population, leading to more accurate and generalizable results in social science research. However, larger sample sizes also require more resources, and in some cases, practical considerations might limit the size of a study.
