Mrs. Alberts has two seventh grade math classes this year. They took their final exam, and Mrs. Alberts just finished grading them. She made a box-and-whisker plot for each class in order to compare their results. Analyze the box-and-whisker plots from above and then select the following comparative inferences that are true. Select all that apply. The interquartile range of Class A is about twice as large as the interquartile range of Class B. There is very little overlap in the two data sets. The median of Class A is about 5 points higher than the median of Class B. The range of Class B is about 12 points less than the range of Class A. A student in Class B had the highest score of both classes. In general, the students from Class B scored better than the students from Class A.
