Many people believe that research has provided conclusive evidence that watching violent television or playing violent video games causes children to behave in more aggressive ways. others have suggested that this relationship is explained in reverse-that children who are more aggressive actively seek out more violent forms of media. this distinction demonstrates the value of remembering the critical thinking concept of

Correlation versus causation

Explanation:

Correlation is measuring the relationship between two variables, their size or direction, and causation is describing one event as a result of another event so it is showing us a relationship between two events. In this case, aggressive children would be a cause of watching and playing violet games, not games themselves.
