A comparison of index of coverage across degree programs. The index of coverage indicates the number of lectures allocated to a lecture theme relative to the number of topics taught. Data are expressed as: $\frac{\mathrm{average}\mathrm{number}\mathrm{of}\mathrm{topic}\mathrm{lectures}\mathrm{per}\mathrm{theme}}{\left(\mathrm{total}\mathrm{number}\mathrm{of}\mathrm{topics}\mathrm{per}\mathrm{theme}\right)\times \left(\mathrm{fraction}\mathrm{of}\mathrm{topics}\mathrm{taught}\mathrm{per}\mathrm{theme}\right)}$. Lecture themes ranked from left to right on the basis of mean lecture theme percentage across degree programs from highest to lowest. An index of greater than 1 represents more than 1 lecture taught per lecture topic.
