The box and whisker plot represents the scores made by two different classes on the same test. By comparing the length of the boxes for the classes, which inference, if any, can you make about the variability of the scores?A) No inference can be made about variability based on the length of the boxes. B) Since the box representing second period scores is about half the length of the box for fourth period, the variability is the same for both periods. C) Since the box representing second period scores is shorter than the box for fourth period, there is less variability in the scores for second period. D) Since the box representing second period scores is shorter than the box for fourth period, there is more variability in the scores for second period.
