  3. Design of experiments - Wikipedia

    en.wikipedia.org/wiki/Design_of_experiments

    The question of design of experiments is: which experiment is better? The variance of the estimate X 1 of θ 1 is σ 2 if we use the first experiment. But if we use the second experiment, the variance of the estimate given above is σ 2 /8. Thus the second experiment gives us 8 times as much precision for the estimate of a single item, and ...

    en.wikipedia.org/wiki/Scientific_method

    The history of scientific method considers changes in the methodology of scientific inquiry, not the history of science itself. The development of rules for scientific reasoning has not been straightforward; scientific method has been the subject of intense and recurring debate throughout the history of science, and eminent natural philosophers and scientists have argued for the primacy of ...

    In the scientific method, an experiment is an empirical procedure that arbitrates competing models or hypotheses. [2] [3] Researchers also use experimentation to test existing theories or new hypotheses to support or disprove them. [3] [4] An experiment usually tests a hypothesis, which is an expectation about how a particular process or ...

    Fisher introduced the null hypothesis by an example, the now famous Lady tasting tea experiment, as a casual wager. She claimed the ability to determine the means of tea preparation by taste. Fisher proposed an experiment and an analysis to test her claim. She was to be offered 8 cups of tea, 4 prepared by each method, for determination.

    The step-by-step procedure, notable observations, and relevant data collected are all included in the methods and results. The discussion section consists of the author's analysis and interpretations of the data. Additionally, the author may choose to discuss any discrepancies with the experiment that could have altered the results.

    en.wikipedia.org/wiki/Preregistration_(science)

    In the standard preregistration format, researchers prepare a research protocol document prior to conducting their research. Ideally, this document indicates the research hypotheses, sampling procedure, sample size, research design, testing conditions, stimuli, measures, data coding and aggregation method, criteria for data exclusions, and statistical analyses, including potential variations ...
