Psychology

1. First, define the key elements of a case study/naturalistic observation. Second, design a case study/naturalistic observation to study either sleep or exercise. Who would you study/Where would you make your observations? What variables would you measure? What results do you expect? What are the limitations of your results?

2. First, define the key features of a correlational design. Second, design a correlational study to study either sleep or exercise. What two variables would you measure? Do you expect a positive or negative correlation? What does that result mean? What other variable(s) (besides the ones you studied) might explain these results? What are the limitations of your results?

3. First, define the key features of an experimental design. Second, design an experiment to study either sleep or exercise. What are your independent and dependent variables? What are the experimental and control group? How would you determine these groups (Be sure to consult your textbook for the specific strategy/label)? What other controls might you consider using in your experiment to strengthen your results? How will you reduce the impact of other variables? What are the expected results and what do they mean?

4. Which of your three studies allows you to determine cause and effect?
