Quizplus · Accepted Answer

The monkeys in the smoky environment were specifically assigned to a group, which suggests that they were part of an experimental design with manipulated variables. Therefore, choice D, experimental, is the best answer. Choice A, correlational, does not make sense because it implies that the study is looking at relationships between variables rather than manipulating them. Choice B, survey, is also unlikely because it suggests that data was collected through self-report surveys rather than controlled experimental conditions. Choice C, control, is partially correct because there likely was a control group of monkeys raised in a smoke-free environment for comparison, but it does not answer the specific question about the smoky environment monkeys.
