A hypothesis-testing experiment involves a methodical approach to investigate a scientific question or prediction. This process typically begins with the formulation of a hypothesis, a testable statement about the relationship between variables. The experiment is designed to collect data that either supports or refutes the hypothesis, utilizing a control group and manipulated variables to ensure validity. Analyzing the results enables scientists to draw conclusions, contribute to knowledge, and refine or restructure hypotheses for future studies. This systematic approach is central to the scientific method.
