A researcher wants to do a correlational study on the relationship between the amount of time spent playing video games and attention span. How might this research be conducted? What are the major disadvantages of this type of research approach?

A correlational study is a type of research method that investigates the relationship between two or more variables without making any cause-and-effect conclusions. It seeks to determine if a correlation exists between the variables and the strength and direction of this relationship. The study usually involves collecting data on each variable and analyzing their association using statistical methods. The results of a correlational study can be used to inform future experiments to determine cause-and-effect relationships.
