Question

Quizplus · Accepted Answer

The basis of an experiment is the manipulation of an independent variable. This is what allows researchers to examine the effects of different conditions and determine cause-and-effect relationships with a dependent variable. A dependent variable is measured or observed in response to changes in the independent variable, so while it is part of the experiment, it is not the basis of it. Option A describes one aspect of an experiment, but not the overall basis. Option D is too broad and not specific to experiments.
