Mahalanobis distance, a multivariate measure of effect, can improve hypnosis research. When two groups of research participants are measured on two or more dependent variables, Mahalanobis distance can provide a multivariate measure of effect. Finally, Mahalanobis distance is the multivariate squared generalization of the univariate d effect size, and like other multivariate statistics, it can take into account the intercorrelation of variables.
