In a correlational study, researchers measure two variables to determine if they change together. if they change together (if they covary), then we can conclude that they might be related to each other. we cannot, however, draw any conclusions about one variable affecting the other because there was no experimental manipulation or control group. you may have heard this described as: correlation does not imply causation. so, here's your question: researchers have found that the ventricles (fluid-filled spaces in the brain) in people with schizophrenia are, on average, larger than the ventricles in people who do not have schizophrenia. what is the most appropriate conclusion?
