Which of the following statements is true?

Question

Quizplus · Accepted Answer

A double-blind experiment is an experiment where both the researcher and subject are unaware of the treatment that a test subject receives. This is different from a single-blind experiment, where only the subject is unaware. Double-blind experiments help to prevent unconscious researcher bias, which means the results will be more accurate, as there is no opportunity for those running the experiment to unconsciously influence or manipulate anything to achieve the desired results.
While it is true that a double-blind experiment is used to reduce researcher bias and increase overall accuracy, this does not necessarily mean that results are always 100% accurate. This is because there can be other unknown or unaccounted variables that influence the results, called lurking variables. However, the results of double-blind experiments will always be regarded as more accurate than those achieved with a single-blind experiment.
Important note: Not all experiments can be double-blind based on the nature of the study.
