WebSep 9, 2024 · To confirm that significant correlations were specific for the reactive aggressive group, we compared whether correlation coefficients were significantly different between the reactive aggressive and the control group using Fisher’s r-to-z transformation (R-based online tool, Diedenhofen and Musch, 2015; Fisher, 1925). WebThe confidence interval around a Pearson r is based on Fisher’s r-to-z transformation. In particular, suppose a sample of n X-Y pairs produces some value of Pearson r.
