Yates’ continuity correction. We often use approximations with continuous probability distributions to solve hypothesis contrasts with variables that follow a discrete distribution. In these cases, we must apply a continuity correction, the best known being the Yates’ continuity correction.
Simple correlation. Correlation is defined as the strength and sense of association between two random variables. Some of the most widely used correlation coefficients are described, such as Pearson’s correlation coefficient, Spearman’s correlation coefficient, and Kendall’s tau coefficient.
Multivariate analysis. Multivariate analysis is the set of statistical procedures that simultaneously study various characteristics of the same subject or entity, in order to analyze the interrelation that may exist among all the random variables that these characteristics represent. The…
