Final answer:
A Research Ethics Board (REB) proposal must state both the probability and magnitude of foreseeable risks to participants, ensuring that they can give informed consent. This includes outlining any potential risks in relation to the benefits and affirming voluntary participation.
Step-by-step explanation:
A proposal to a Research Ethics Board (REB) must clearly state c. Both the probability and the magnitude of foreseeable risks to participants. This is essential for ensuring that participants are able to give informed consent.
Key ethical requirements that are mandated by law for studies involving human participants include minimizing risks to study participants while ensuring they are reasonable in relation to the benefits. The Institutional Review Board (IRB) oversees that these requirements are met.
Moreover, when a statistical study uses human participants, it's critical to disclose all risks and benefits, guarantee the safety of participants, and affirm that participation in the study is completely voluntary.
