Question

Quizplus · Accepted Answer

The null hypothesis for this study would be that the new drug, Focus, has no significant impact on the symptoms of attention deficit disorder compared to a control group receiving no treatment. This is the base assumption that the research team sets out to challenge with their study. Option B is incorrect as objective measurement of the dependent variable is a requirement for all research, not just the null hypothesis. Option C is also incorrect as blinding is a requirement for minimizing bias in experiments and is not unique to the null hypothesis. Option D is irrelevant to the null hypothesis and concerns differences between the control and experimental groups, not the drug's effectiveness.
