BOZA TORRES, Pedro Emilio; LIRIANO LEYVA, Oslaidis; PEREZ SANCHEZ, Yaderine y FONSECA GONZALEZ, Ramón Luis. Practical guide to select a statistical test to apply in biomedical research. Multimed [online]. 2022, vol.26, n.6 Epub 26-Nov-2022. ISSN 1028-4818.
Introduction:
statistical analysis is divided into two components: descriptive analysis and inferential analysis, statistical tests, are divided into parametric and nonparametric. Choosing an appropriate statistical test, however, is challenging.
Objective:
to propose a tool, which serves to select a statistical test to those not experts in biostatistics, for biomedical research.
Methods:
a narrative literature review study was conducted. It was based on a review of the literature on the main statistical tests currently used, available in the literature of bibliographic databases such as Pubmed/Medline, SciELO, SCOPUS, Springer, Web of Science, EBSCOhost among others. This tool was validated by expert criteria.
Results:
a scheme was designed, which can be used in two ways: the first is to follow the scheme until discovering which is the appropriate statistical technique for your data and the second: following the scheme backwards, determine if the test was a logical choice for the analyzed data. To use it, you must identify dependent and independent variables, then you will arrive at a synthesis measure or a useful point estimate for your data, which will be followed by a general classification of statistical tests.
Conclusions:
the proposed guideline is an attempt to provide a useful guide to select a statistical technique for data analysis in biomedical research.
