WGU Data-Driven Decision Making (C207) Exam - Topic 2 Question 14 Discussion

Cumulative incidence is the proportion of a population initially at risk that develops a condition during a specified period. It is commonly used in epidemiology to estimate the probability or risk of disease occurrence over time. In this question, the correct Year 2 cumulative incidence rate is 11.84 percent. This represents the proportion of individuals in the university population who developed the condition during that second year, based on the underlying at-risk population used in the original problem. Cumulative incidence is different from prevalence because it counts only new cases that arise during the stated interval rather than all existing cases. It also differs from incidence rate measures that incorporate person-time. Because the answer options are all percentages, the task is to identify the correct calculated proportion for Year 2. Based on the provided choices, 11.84 percent is the correct cumulative incidence value. Therefore, the correct answer is 11.84 percent.
