摘要

It is often of interest to compare the concentration of two distributions. For example, the so called "external efficacy" of two different doctorate courses can be assessed by comparing the heterogeneity of the range of job opportunities of-fered by each. Obviously the most effective course is the one that offers the wid-est and therefore most heterogeneous range of job opportunities. In this matter, from a statistical point of view, job opportunities represent the nominal categori-cal response variable and the two populations consist of all the students who have achieved a doctorate in one course or the other. A sampling survey aimed at determining the kind of job Ph.D. graduates attain as their first post, could pro-vide the initial data useful in resolving the above issue.
