What happens when more than one variable is manipulated in an experiment?
If scientists change only one variable and observe a corresponding change in a dependent variable, they can begin to establish some causal mechanism between the two. It is also possible to analyze the effects of multiple independent variables at once. This technique is called
multiple regression
