Experimentation is a systematic process used to test hypotheses and explore new ideas. It involves manipulating variables to observe the effects and gather data. This method is fundamental in fields like science, psychology, and engineering, allowing researchers to validate theories and discover new phenomena. In an experiment, researchers typically start with a question or problem, then design a procedure to test their ideas. They collect and analyze data to draw conclusions, which can lead to further questions and additional experiments. This iterative process is essential for advancing knowledge and innovation in various disciplines.
