Question

Quizplus · Accepted Answer

The best research design for this study is epidemiological since it focuses on identifying patterns and associations within populations. This design will allow researchers to study a large number of low-income American children and their lifestyle factors without manipulating any variables, while also enabling them to make inferences about causal relationships between lifestyle factors and delayed physical growth. Double-blind, interventional, and human in-vivo experimental designs all involve manipulating variables, which is not suitable for this type of study.
