The Experimental Method is a systematic approach used in scientific research to test hypotheses and observe outcomes. It involves manipulating one or more variables while keeping others constant to determine cause-and-effect relationships. Researchers typically conduct experiments in controlled environments to minimize external influences. In an experiment, the group receiving the treatment is called the experimental group, while the group that does not receive the treatment is known as the control group. By comparing results from both groups, scientists can draw conclusions about the effects of the variable being tested, contributing to the body of knowledge in fields like psychology, biology, and chemistry.
