What is the difference between experimental replicates and experimental controls?

Question

Quizplus · Accepted Answer

Experimental replicates are repeat samples taken under the same experimental condition, in order to ensure the accuracy and reliability of the results. Experimental controls, on the other hand, are samples used to ensure that any observed effects are due to the experimental treatment and not other factors. The two terms are not interchangeable, and serve distinct purposes in experimental design. Option B is incorrect because replicates actually increase the sample size, which improves statistical power. Option C is incorrect because replicates can be found both under control and experimental conditions. Option D is incorrect because replicates should be identical in all factors except for the variable being tested, so as to eliminate unwanted variation.
