Which of the following is NOT a typical function of an IRB?

The correct choice reflects that providing researcher training in statistical methods is not a typical function of an Institutional Review Board (IRB). An IRB's primary responsibilities involve the ethical oversight of research involving human subjects, which includes activities such as reviewing research protocols to identify and assess potential ethical concerns, monitoring ongoing research to ensure compliance with agreed-upon protocols, and ensuring that participant consent procedures are properly implemented and respected.

While IRBs focus on the ethical dimensions of research, such as safeguarding participant rights and welfare, they do not provide training in statistical methods or research methodology. This training is generally the responsibility of academic institutions or research organizations, which equip researchers with the necessary skills to design and analyze studies effectively. Thus, the correct answer highlights the specialized role that IRBs play in maintaining the integrity of research involving human participants, distinguishing it from educational roles concerning statistical training.
