The smallest slice of the blueprint and the one most people under-study — which is exactly why it moves your score. Epidemiology, biostatistics, the dental indices, levels of prevention, and how to read a study. Answer, and the reasoning lands immediately.

• ✓Epi and biostats made concrete. Incidence vs prevalence, sensitivity and specificity, data types, and central tendency — with real numbers to work.
• ✓Type the calculation. Several items make you compute the answer and enter it — sensitivity, incidence, mean DMFT — no options to reverse-engineer.

• ✓Feeds your dashboard. Your score rolls into your Community readiness — a domain nothing else here drills directly.
