Introduction
This document contains comprehensive NSG 522 Epidemiology and
Biostatistics final exam preparation material covering
epidemiologic concepts, study designs, disease occurrence
measures, prevention, infection transmission, surveillance, vital
statistics, risk measures, screening, and diagnostic test
characteristics. It includes practice questions with verified answers
as well as detailed review material on epidemiology, biostatistics,
causal inference, outbreaks, and evidence-based research methods.

retrospective study select all that apply
