SANCHEZ TURCIOS, Reinaldo Alberto. Demystification of the significance of p in statistical tests. Rev. Mex. Cardiol [online]. 2015, vol.26, n.1, pp.56-58. ISSN 0188-2198.

All statistical tests have a p value that is significant when < 0.050. This value was arbitrarily determined by RA Fisher and accepted consensually over time. Since its genesis, this value has been questioned, and nowadays it is under the careful eye of many statisticians. This issue has led to a debate among the scientific community: obtaining p significance was considered as a guarantee that the research project would be an appropriate contrast between the hypothesis and the acceptance, or rejection, of it. The purpose of this paper is to construct a discussion about p significance.

Palabras llave : Statistic test; p value; p significance.
