A research team investigated whether there was any significant correlation between the severity of a certain disease runoff and the age of the patients.
The formula for the test statistic is t r n 2 1 r2 t r n 2 1 r 2. We can use theorem 1 to test whether the correlation coefficients of two populations are equal based on taking a sample from each population and comparing the correlation coefficients of the samples. Finally we perform either one of the following tests. As an example suppose you computed r 0 801 r 0 801 using n 10 n 10 data points.
