Question

Quizplus · Accepted Answer

To make a causal claim, Stefan must conduct an experiment to manipulate his independent variable and measure the effect on his dependent variable. This is the only way to establish a cause-and-effect relationship between variables. Making a frequency claim or simply measuring variables without manipulation would not allow for a causal claim.
