What are the three principles of experimental design ? There are three principles of experimental design that help scientists to accurately measure the results of an experiment: control, replication, and randomization. In this article, we will discuss each of these principles in detail.

What are the three principles of experimental design ?

Control: A control is an essential part of any experiment. It is the standard by which you will measure the results of your experiment. Without a control, you would not be able to determine if your experimental treatments had any effect on the outcome of your experiment.

Replication: Replication is another important principle of experimental design. Replication means that you repeat your experiment several times, using different subjects or different treatments. This allows you to confirm the results of your original experiment and to rule out any chance effects.

Randomization: Randomization is the third principle of experimental design. Randomization means that you assign your subjects to different treatment groups by chance, rather than by choice. This ensures that any differences between the groups are due to the experimental treatment and not to other factors, such as the subjects’ personalities or the order in which they received the treatments.

By following these three principles of experimental design, scientists can be confident that their results are accurate and that their experiments are fair.
