The key to the success of the experimental method is to hold all extraneous variables constant. This ensures that any differences observed between the groups are due to the manipulation of the independent variable and not some other factor. Randomly selecting a very large sample of participants may not necessarily be important for the success of the experimental method, but it can increase the generalizability of the results. Manipulating as many variables as possible is not a good idea as it can lead to confounding variables and it becomes difficult to isolate the effect of the independent variable. Allowing extraneous variables to only influence the treatment group is not a good way to ensure the internal validity of the experiment.
