Scientists use the scientific method because it is evidence-based, standardized and objective in conducting experiments. The scientific method allows scientists to stick to facts and to avoid the influence of preconceived notions and personal biases in research processes, improving the credibility of research findings.
The scientific method minimizes the influence of personal experiences and cultural beliefs on the experimenter. It also allows scientists to accept the outcome of research without filtering data or information. Scientists use the scientific method to test hypotheses or solutions and to answer questions. The scientific method involves a rigorous methodology that is aimed at minimizing prejudice. However, scientists still make errors, such as mistaking a hypothesis with a solution or explanation of a phenomenon.
Scientists use the scientific method to interpret or correct previous knowledge, to acquire new knowledge or to investigate issues. The scientific evidence is based on measurable or empirical evidence, which is reliable in solving problems. The procedures of the scientific method vary from one field of study to another, but there are common features shared by various disciplines. The scientific method involves systematic techniques of observation, testing, formulation, experimentation and measurement. The scientific method is also used in establishing theories or proving them wrong. Scientists also use the scientific method to modify theories or to discard them. The steps of the scientific method include making an observation, asking a question and formulating a hypothesis.
