Quizplus · Accepted Answer

A correlational study was used in this study, as the researchers were analyzing the relationship between two variables (musical ability and mathematical aptitude) without manipulating any variables. There was no experimental manipulation or intervention, so it cannot be an experiment. It was also not a case study, as there were multiple participants involved, not just one individual being studied in depth. And, while there was some observation involved in collecting data, the focus was on analyzing the correlation between the two variables, not simply observing behavior.
