Upon completion of this exercise students will be able to: Define an observational study. Describe the distinguishing components of an experiment. Identify an investigation as either an observational study or an experiment. Suggest an experiment that could be created based on findings from an observational study. Materials: Get Statistics lesson plan. “Let’s Healthy” TI-83, 84, or Inspire calculator. Student copy of Information and Questions for Exercise 1 Teacher Key and Comments for Exercise 1 Preparation: Copy enough sets of questions for your class or be prepared to project the descriptions and have students write the questions down. Activities/Procedures: Step 1 Pass out student sheet for this exercise. – Step 2 students complete sheet for Exercise one either individually, with a partner or a small group –Have depending on instructor preference. Review answers with students with special emphasis on the experimental design question. This is Step 3 – an especially useful time to have students compare their designs with each other to identify strengths and weaknesses of their proposed experiments. Assessment/Reflection: Up to instructor. Assignment can be turned in, checked off or scored by student during discussion and review. Similar concepts are typically covered in multiple choice or open-ended form on most unit or cumulative tests dealing with this area of statistics. Resources: School adopted AP Statistics Textbook and associated sections on collecting data using observational studies and experiments. Standards: This lesson meets part of the Collecting Data syllabus portion of the Advanced Placement Statistics course.
