Question

Quizplus · Accepted Answer

Choice B is a causal-comparative research question because it compares the endurance of two different groups (year-round swimmers vs summer swimmers) after 12 weeks of winter practice. The question looks for potential causal factors that may influence endurance. The other choices do not clearly compare two groups or investigate potential causal factors.
