scientific method(redirected from Critical method)
Also found in: Dictionary, Thesaurus, Encyclopedia.
The principles and empirical processes of discovery and demonstration considered characteristic of or necessary for scientific investigation, generally involving the observation of phenomena, the formulation of a hypothesis concerning the phenomena, experimentation to test the hypothesis, and development of a conclusion that confirms, rejects, or modifies the hypothesis.
a systematic, ordered approach to the gathering of data and the solving of problems. The basic approach is the statement of the problem followed by the statement of a hypothesis. An experimental method is established to help confirm or negate the hypothesis. The results of the experiment are observed, and conclusions are drawn from observed results. The conclusions may tend to uphold or to refute the hypothesis.
scientific methodthe way of approaching a problem by drawing up a hypothesis based on a series of observations, and then testing the hypothesis by means of experiments designed in such a way as to support or invalidate the hypothesis. On the basis of the experimental evidence a theory is proposed to account for the initial observations. If subsequently the theory is found to be wanting in some respect, new hypotheses are sought and tested experimentally, so the process is a successive refinement which in science never leads to an absolute truth, but to a more reliable knowledge.
n a formal style of study or research in which a problem is identified, pertinent information is assembled, a hypothesis is advanced and tested empirically, and the hypothesis is accepted or rejected.
the process of extending knowledge by forming a hypothesis based on observations and epidemiological patterns, which is then tested on a subset of the total population, then generalizing the results to the appropriate population through the process of inductive logic. Before implementation of the hypotheses they should be tested by studies planned on the basis that the hypothesis will be proved or denied.
