Assume that the average rating in each of the three classes is 5 (by looking at the three histograms, this seems reasonably clear).  And recall the interpretation of the Standard Deviation as a "typical" or "average" distance between the data points and their mean. Answer these questions by judging from the table and the histograms.  Do NOT actually calculate the Standard Deviation.

Which class would have the largest Standard Deviation?   

Which class would have the smallest Standard Deviation?
