Math 243Reflection 2Section 1.3Experiments to Determine Causation

Does one "hit" of cannabis affect reaction time for community college students over 21 years old?You will be asked to design two experiments to determine the answer to this question.Here are the "tools" that you have been given to create these experiments.

The reaction-time app we used in class.

28 community-college-student volunteers who are over 21 years old.

1.What is the explanatory variable, what is the response variable?

2.a)Design a randomized comparative experiment to answer this question. Say how you're randomizing the explanatory variable.In this situation, I am not sure if a placebo can be used. People know when they're stoned or not.

b)Design a matched pairs experiment to answer this question.

3.Is it likely that the sample (the cases in your study) is representative of Community College students in general?Explain your answer.(This is not just about sample size.)
