Which of the following is a strength of experiments? They allow for the establishment of cause-effect relationships. They are not subject to demand characteristics since the subjects do not know they are being observed. They allow us to draw definitive conclusions about behavior in the natural environment based on subjects' behavior in the laboratory. They cannot be repealed by any person other than the scientist. They cannot be repeated by anyone other than the experimenter.

Answer: They allow for the establishment of cause-effect relationships.

They allow us to draw definitive conclusions about behavior in the natural environment based on subjects' behavior in the laboratory.

Explanation:

An experiment is a process which is can be define as the procedure to test the hypothesis either to refute, validate and prove it. The experiments are based on the repeatable trials so as to determine the results which match with the statements of the hypothesis.

The following are the strengths of an experiment:

They allow for the establishment of cause-effect relationships. : The experiment involves the analytical procedure, which involves the determination of the change made over one variable (independent) is likely to cause change over the other variable (dependent variable), which is the outcome of the experiment.

They allow us to draw definitive conclusions about behavior in the natural environment based on subjects' behavior in the laboratory. : An experimental procedure involves the mimicking of the experimental setup as that of a natural process. This will lead to production of conclusion for the cause of natural processes.
