Question

Quizplus · Accepted Answer

Experimental control involves manipulating variables to eliminate alternative explanations for the findings. This process helps ensure that any observed effects are due to the independent variable and not some other factor in the environment or the participants. Placebo effectiveness refers to the impact that belief or expectation can have on treatment outcomes and is not directly related to ruling out alternative explanations. Non-random assignment and interactive subjectivity are also not directly related to the process of ruling out alternative explanations.
