According to the leadership literature, there are a number of different leadership styles. Listed below are scores obtained from an instrument designed to measure a particular leadership style, which will be referred to as style X. Of interest is whether X differs by school district type in terms of urbanity, and by years of experience. A stratified random sample of school principals were selected from three district types (mostly urban, mostly suburban, and mostly rural). The scores on style X range from 100 to 0. The closer the score to 100, the more the respondent conforms to style X, while the closer the score to 0, the less the respondent conforms to style X.

Is there any evidence that X differs among the three district types, once years of experience is taken into account?
