(AKS 23): Mr. Smith looked at the scores from 2 different Math classes, as shown on the dot plots below. When comparing the two sets of scores, what conclusion did Mr. Smith draw about the center and spread of the data of class scores? (Hint: measures of center: calculate the mean and median; measures of spread/ variability: calculate the range, IQR, and standard deviation.)
