Clare recorded the amounts of time spent doing homework, in hours per week, by students in sixth, eighth, and tenth grades. She made a dot plot of the data for each grade and provided the following summary. Students in sixth grade tend to spend less time on homework than students in eighth and tenth grades. The homework times for the tenth-grade students are more alike than the homework times for the eighth-grade students. Use Clare's summary to match each dot plot to the correct grade (sixth, eighth, or tenth). Description:
Three dot plots, time in hours, 10 to 22 by ones. Dot plot A, starting at 14, the number of dots above each increment is 1, 1, 2, 3, 3, 4, 3, 3. Dot plot B, starting at 11, the number of dots above each increment is 1, 0, 3, 2, 2, 4, 3, 3, 1, 1. Dot plot C, starting with 16, the number of dots above each increment is 2, 6, 9, 2, 1.
