Which of your three studies allows you to determine cause and effect?.
Design a naturalistic observation to study either sleep or exercise. Where would you make your observations? What variables would you measure? What results do you expect?
2. 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?
3. Design an experiment to study either sleep or exercise. What are you 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?
