A researcher thinks that watching violent televisions increases aggressive behavior in children. To test this hypothesis, she randomly assigns 48 children into one of 3 groups (no violent TV, a little violent TV, or a lot of violent TV) and observes their playground behavior for three weeks and measures it for violence and intensity. The variable “amount of TV” (as it appears in this problem) is a __________ variable. a. continuous b. discrete A researcher thinks that watching violent televisions increases aggressive behavior in children.
