Exam Scores: Handling Data 1. The following is a list of your class's exam scores, out of 100 possible points. 81 47 67 69 76 88 67 67 69 70 38 84 69 70 72 73 71 68 74 95 77 79 94 69 75 67 71 72 70 68 75 74 72 85 76 How can you organize this data to understand it better? If someone asked you how your class did, how could you summarize the information? (Or would you just hand them the list of test scores you recorded?) Here are a few more questions to think about. (a) Are there helpful ways of representing the scores visually? Try to come up with more than one way, apply each to your data, and discuss the advantages and disadvantages of each. (b) What words would you use to describe this data set to another teacher? What features do you think are important? Try to be as precise as possible. (c) Can you come up with any numbers that might help quantify your words? (d) How might you go about assigning grades to scores? Make an assignment and explain why you choose it. (e) What might you conclude about your class's understanding? 2. Suppose instead that the list of scores looked as follows. Answer the same questions as before, but this time with an eye for what helps you understand how these two data sets are different. 80 81 81 81 69 80 82 66 76 73 78 72 81 77 79 79 94 82 81 79 78 99 79 82 65 81 71 76 76 77 78 80 75 79 82
