A professor has a large class (250 students) that meets at 9am three days a week. The professor was curious about how eating before an exam affects the students ability to recall information. Before the first exam, the class was divided into two equal groups. The first group was told to eat a full, balanced breakfast 1-3 hours prior to the exam, while the second group was told to skip breakfast entirely the morning of the exam. The graph below depicts the results. Use this information to answer the questions to the right. What was the prediction of this experiment? The Basics of Scientific Investigations Last week you learned about the process of scientific investigation and the characteristics of a well-designed study. This exercise will encourage you to apply what you learned. The scenario: A professor has a large class (250 students) that meets at 9am three days a week. The professor was curious about how eating before an exam affects the students ability to recall information. Before the first exam, the class was divided into two equal groups.
