The positive control confirms that the basic conditions of the experiment were able to produce a positive result, even if none of the actual experimental samples produce a positive result. The scientific method is a set of procedures and principles that guide how scientists develop research questions, collect data and come to conclusions. In order to compare the effectiveness of two different types of therapy for depression, depressed patients were assigned to receive either cognitive therapy or behavior therapy for a 12-week period. Experimentation is the best known way to test the veracity of scientific theories, eliminate alternative explanations, engineer novel solutions to practical problems, and provide clues to causal inference.
