Scientists use reasoning to design an experiment to test their . Scientists develop a good experimental design that contains both a group in which the experimental variable is altered, and a group in which the experimental variable is not altered. Occasionally, scientists are forced to use a to represent the actual phenomenon, usually because of ethical, financial, or logistical limitations. The results of an experiment are called and must be analyzed in order for a to be reached.
