Question

Quizplus · Accepted Answer

The independent variable is the amount of the new memory drug given to the participants, and the dependent variable is the quiz scores, which are being measured in response to the amount of exposure to the drug. Option A is incorrect as it refers to the response to the drug, which is not the same as the amount of exposure to it. Option B is incorrect as it refers to experimental design rather than the specific variables being investigated. Option D is incorrect as researcher variables and extraneous variables are not relevant in this scenario.
