Question

Quizplus · Accepted Answer

Roberto used a multiple time-series design, also known as a pre-post design with a control group (the states that did not implement seat belt laws), to compare the differences in deaths before and after the implementation of seat belt laws. This design is commonly used in program evaluation to assess the impact of interventions. The other options (true experimental design, survey design, cost-benefit analysis, and longitudinal design) do not accurately describe the design used by Roberto.
