Do the lengths of boys’ names have more variation than the lengths of girls’ names? With current names like “Nathaniel” and “Christopher” versus “Ian” and “Jack,” it certainly appears that boys’ names cover a wide range with respect to their length. To test this theory, random samples of seventh-grade girls and boys were taken.
At the 0.05 level of significance, do the data support the contention that the lengths of boys’ names have more variation than the lengths of girls’ names?
