Question

Quizplus · Accepted Answer

In order to make a causal claim, a researcher must conduct an experiment where they manipulate the independent variable and measure the effect on the dependent variable. This is the only way to establish a cause-and-effect relationship. While measuring and manipulating variables may be important aspects of the experimental process, they are not sufficient on their own to make a causal claim. A frequency claim is not relevant to making a causal claim.
