A researcher uses the data from Problem 2 to investigate whether there is more variation among boys or girls in attitudes about whether social media encourages bullying. She finds that the range is 10 for boys and girls. However, the standard deviation is 5.5 for boys and 2 for girls.

a. Based on the range and the standard deviation, is there more variation among boys or girls in attitudes about the role of social media in bullying?

b. The overall sample was split evenly between boys and girls. But, only twenty girls in the sample gave a response of 0, 1, 2, or 3 (disagreed that social media encourages bullying), compared to 115 boys. Is the range or standard deviation a better indicator of variation among boys? Girls?
