The double dot plot shows the heights in inches for the girls and boys in Franklin’s math class. Compare the centers and variations of the two populations. Round to the nearest tenth. Write an inference you can draw about the two populations.
Both plots are symmetric. The girls’ heights have a mean of 65 inches with a mean absolute deviation of about 0.8 inch. The boys’ heights have a mean of 69 inches with a mean absolute deviation of about 1.4 inches. Overall, the girls’ heights are lower than the boys’ heights and are also more consistently grouped together.
