Quizplus · Accepted Answer

The test with 50 questions would have the greatest sensitivity to detect an effect because it provides the most opportunities for the effect to be measured and detected. As the number of questions increases, the test becomes more comprehensive and has a higher likelihood of detecting a true effect, even if it is small. A test with only one question or few questions may miss subtle effects, while a test with more questions can increase the chances of detecting a significant effect.
