Is there a direct link between sleep and academic success?

What area of interest/research question do you wish to explore through a research study design? I’m interested in the role sleep plays in our grades.
What variables or concepts are you looking to observe and/or manipulate? The number of hours a student slept would be manipulated.
What type of design would best suit your research question? (Experimental, Correlational, etc) Experimental
What research method would you use to conduct your experiment? (Survey, case study, naturalistic observation, lab experiment, etc.) Random assignment of participants in their natural environments.
If applicable, what would you put as your independent and dependent variables? The number of hours slept would be the independent variable while the final grade in the class would be the dependent variable.
Give a hypothesis about what you think you might find. I predict that students who sleep more will do better in the class.
What might be the benefits and implications of this study? In other words, who would gain from it? Everyone would benefit from this study.
Please reflect on the process of designing this experiment. What were the challenges you faced? Was this more/less difficult than you expected? How? A challenge would be the differences in the student’s behaviors. Not all students are the same. This makes it more difficult than I expected because it’s almost impossible to find two or more students who are alike.
