When one variable causes change in another, we call the first variable the ___________________ variable*. The affected variable is called the _______________ variable*. When one variable causes change in another, we call the first variable the explanatory variable*. The affected variable is called the response variable*. In a randomized experiment, the researcher manipulates values of the explanatory variable and measures the resulting changes in the response variable. The different va...
