Using Crossover Design, the next week we switched the groups giving students who previously took the placebo the Adderall for the new test to see how it affected their test scores

With a Sample size of 500, our margin of error is 4.5% This is a low margin of error which means that our results should be a good representation of all students

We are bale to bling all of the students, those taking the placebo do not knacks they are taking the placebo, those taking the Adderall do not know if they are taking the Adderall or the placebo. This is not double blind because we, the ones holding the experiment know who is taking what

We will replicate this study in the next semester with another 500 students.
