Question
A group of researchers investigated the effects of two vocabulary learning strategies on word retention two weeks later. In this example, learning strategy is the ________ variable and word retention is the ________ variable.
Solution
In this example, the learning strategy is the independent variable and word retention is the dependent variable.
Here's why:
-
Independent Variable: This is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. In this case, the learning strategy is what the researchers are changing or manipulating.
-
Dependent Variable: This is the variable being tested and measured in a scientific experiment. The dependent variable is 'dependent' on the independent variable. In this case, word retention is being measured after the learning strategy is applied, so it is dependent on the learning strategy.
