10) Weinstein, McDermott, and Roediger (2010) published an experimental study examining different techniques that students use to prepare for a test. Students read a passage, knowing that they would have a quiz on the material. After reading the passage, students in one condition were asked to continue studying by simply reading the passage again. In a second condition, students answered a series of prepared questions about the material. Then all students took the quiz. The following table shows quiz scores similar to the results obtained in the study. Sketch a polygon showing the frequency distribution for students who reread the passage. In the same graph, sketch a polygon showing the scores for the students who answered questions. Use two different colors or use a solid line for one polygon and a dashed line for the other. Does it look like there is a difference between the two groups?
