Performing randomization test using minitab 18 counts software#
The statistical analysis section should therefore include the following: 1) stating of the statistical analysis methods used, 2) rationale for and detailed description of these statistical analysis methods, 3) presentation of the statistical parameters produced by the statistical analysis methods, 4) type and version of the statistical software package used, 5) significance level, and 6) sidedness of the statistical test (one-sided vs. Readers should be able to reproduce the statistical analysis of a study if the raw data are provided.
The statistical analysis software used, pre-set significance level, and sidedness of the test (two-sided or one-sided) should also be easily determinable by the readers. By reading the statistical analyses described in the methods section, readers should be able to understand what statistical analysis methods were used in the study, the reasons they were used, and the parameters presented as results. Accordingly, researchers must describe the statistical analyses in detail in the methods section of research proposals, results reports, theses, or articles. Therefore, it is necessary to describe clearly and specifically the statistical analysis methods used, how they were used, and the parameters derived from the statistical analysis methods. In particular, several journals require authors to be vigilant not only about performing statistical analyses, but also about providing raw data for their research.

It is essential that the sidedness be described in research studies.
Authors tend not to describe the sidedness of statistical analysis tests in the methodology section of clinical research articles. However, only 4 articles (12.9%) fully described the sidedness of the test (score of 3). In all the included articles, the statistical analysis methods used were stated (score of 3). The first 3 items evaluate issues directly related to the statistical analysis methods used and last 3 are indirectly related items. Using a Likert scale where 1, 2, and 3 represented “not described at all,” “partially described,” and “fully described,” respectively, the following 6 items were assessed: 1) stating of the statistical analysis methods used, 2) rationale for and detailed description of the statistical analysis methods used, 3) parameters derived from the statistical analyses, 4) type and version of the statistical software package used, 5) significance level, and 6) sidedness of the test (one-sided vs. We evaluated the quality of the statistical analysis sections of clinical research articles published in the Korean Journal of Anesthesiology between February 2020 and February 2021. It is also essential for scientific accuracy and transparency in scientific research. Describing statistical analyses in precise detail is as important as presenting the dosages of drugs and methodology of interventions. Researchers who use the results of statistical analyses to draw conclusions about collected data must write a statistical analysis section in their manuscript.
