Mrs. Smith has taught three Algebra I classes this year. She just finished grading her final chapter test for the second semester. The raw data is below:

Class A Class B Class C
80 72 100
85 90 90
87 85 94
92 84 100
86 91 75
90 78 30
94 94 94
100 86 72
75 82 85
45 78 87
85 86 42
38 78 100
72 95 90
94 90 94
62 88 60
Analyze and compare the data for Class B and Class C.

Part 1: Make a dot plot for each of Classes B and C.
Part 2: What information is easily seen from the dot plots for Classes B and C?
Part 3: Look at the box plot and dot plot created for Class B.
