Question

Quizplus · Accepted Answer

Involuntary participants are those who were forced or coerced into participating in the study, and voluntary participants are those who agreed to participate on their own accord. These groups may not represent the larger population, which can threaten the generalizability of the laboratory study. Nonvoluntary participants are not necessarily forced or coerced, so they are less likely to threaten generalizability. Option A) is redundant as involuntary and nonvoluntary are essentially the same concept. Option D) cannot be correct because at least one of the options must be correct.
