Quizplus · Accepted Answer

Internal validity refers to the extent to which changes in the dependent variable are due to the treatment variable and not to other factors. Therefore, the best choice is B because it captures this definition accurately. Option A refers to external validity, which is a different concept. Option C is too vague and subjective, as the value of a study can be evaluated differently by different scientific communities. Option D is a vague and incorrect option that does not offer any relevant information.
