1. The problem involves analyzing the quiz scores of students in two math classes, each with 9 scores represented in dot plots. 2. Since the dot plots are not provided, we cannot calculate exact statistics but can explain how to analyze such data. 3. Important measures include the mean (average), median (middle value), mode (most frequent score), and range (difference between highest and lowest scores). 4. To find the mean, sum all scores and divide by 9. 5. To find the median, arrange scores in order and select the 5th score. 6. To find the mode, identify the score(s) that appear most frequently. 7. To find the range, subtract the lowest score from the highest score. 8. These measures help compare the performance and variability between the two classes. 9. Without the actual scores, we cannot compute these values but this is the method to analyze dot plot data.
