PART II: FREE RESPONSE 1. When students in Long Island City High School complete the Algebra II course, they have a choice in the next math class they take. Students may choose between AP Stats, taught by Mr. Tsai, and AP Calculus, taught by Mr. Phillip and Mr. Soto. The principal of the school wants to determine if there is a difference in the intelligence of the students taking the two courses. Therefore, at the end of the year, the principal will compare the grades the students receive on their final report cards. Is the scenario an example of an experiment, or an observational study? Explain in context of the problem. At the end of the year, it is found that the average grade received by students in AP Calculus was 79.5, while the average grade received by students in AP Statistics was a 77.2. The principal concludes that the students in AP Calculus must be smarter. However, many confounding variables may exist. Discuss two possible confounding variables and how they may affect the results. Due to the many possible confounding variables (including the ones you stated above), the principal decides the fairest way to compare the intelligence of the two groups is to evaluate the AP scores of the students since everyone will be taking the exam in May. Is this a fair method to determine which group of students is smarter? Explain why or why not. PART II: FREE RESPONSE 1.
