Mr. Hanley and Ms. Balch gave an identical Algebra final exam to their classes. The histograms show the distribution of the scores for each class. In 1 simple sentence, compare the histograms and explain which class you think performed better on the exam. Use information from the histograms such as data skew as well as median scores for both classes to justify your response.
