Answer:
The independient variable in this study is the memory-enhancing drug that Dr. Bonne DeMuth is testing on the students.
Explanation:
In research studies, there are independent variables which are those that are being studied and analyzed. When these variables are intervened, these will be the ones that will directly affect the results.
So , in this case Dr Bonne DeMuth is trying to find out if a memory-enhancing drug would help decrease the time it takes students to learn how to trace a maze.The independent variable in this case would be the drug analyzed by Dr Bonne DeMuth and the intervention that is being carried out on this variable is to know if it can achieve the desired effect(decrease the time it takes students to learn how to trace a maze).
