Question

Quizplus · Accepted Answer

In a manipulative experiment, researchers intentionally manipulate the independent variable to observe its effect on the dependent variable. This is typically done in a controlled environment where other variables are held constant to ensure that observed changes are due solely to the manipulated variable. Choice A is incorrect because manipulating too many variables can lead to confounding variables that make it difficult to interpret any observed effects. Choice B is incorrect because replicating the experiment is necessary to confirm and generalize the findings. Choice C and D are incorrect because the peer review process ensures that experiments are conducted ethically and with scientific rigor, and the motive behind an experiment should not be solely for economic gain.
