Question

Amairani Duarte · Accepted Answer

Final Answer : B, Explanation :  Correlational research is the most effective research method for Aaron's study because it examines the relationship between two variables without manipulating them. This will allow Aaron to determine if there is a relationship between sleep deprivation and hours spent on a computer, without making any assumptions about causation. Surveys and case studies may also provide useful information, but correlational research is specifically designed for this purpose. Experimental research, on the other hand, would require manipulating one variable and measuring the effect on the other, which is not necessary for Aaron's research question.
