WebTwo, the provided formula for calculating r uses simple averaging [.5(r 1 +r 2)]. To yield a more accurate indicator of r, I have used Fisher's r-to-Z tranformation, averaged, and reversed back from Z-to-r. Nonetheless, the computation of s in the Z 1 * formula is relatively robust against minor deviations. In using this calculator, you are ... http://www2.psych.purdue.edu/~gfrancis/calculators/fisher_z.html WebResults. When the P-value is less than 0.05, the conclusion is that the two coefficients are significantly different. In the example a correlation coefficient of 0.86 (sample size = 42) is compared with a correlation coefficient of 0.62 (sample size = 42). The resulting z-statistic is 2.5097, which is associated with a P-value of 0.0121. high quality ash bookcase
