How did the two classes compare on the reading test?

Statistics is the science of organizing and analyzing information to make informed decisions. The following are reading scores for two fifth grade classes. For each class’s scores, organize the data, find the mean, mode, median, quartiles, and range, and draw a box and whisker graph for each class using a single number line.

Analyze your results. In sentence form, answer: How are the classes’ scores alike, and how are they different. How would you approach instruction for the classes, the same or different?
