Yes, indeed. A z-test for comparing sample correlation coefficients allow you to assess whether or not a significant difference between the two sample correlation coefficients. ρ 2. that are different from each other. The null and alternative hypotheses to be tested in this case are: H a: ρ 1 ≠ ρ 2. You will reject the null hypothesis when ...

Apr 09, 2015 · Imagine that I've got two datasets where on each I do a correlation between Land Surface Temperature and an urban metric. The datasets are different in their length, so the first one has round about 160.000 observables and the second one has about 2400 observables. For the correlation on the first dataset I get a Pearson of -0.74 and for the second I get -0.885. Now I want to find out whether these coefficients are significantly different from each other.

When conducting correlation analyses by two independent groups of different sample sizes, typically, a comparison between the two correlations is examined.

How can I test whether two correlations are significantly different from ... i.e. a test of the difference between dependent correlations.

Two Correlation Coefficients. Using the Fisher r-to-z transformation, this page will calculate a value of z that can be applied to assess the significance of the difference between two correlation coefficients, r a and r b, found in two independent samples. If r a is greater than r b, the resulting value of z will have a positive sign; if r a is smaller than r b, the sign of z will be negative.

Comparing Correlation Coefficients. Quantitative Results. Statistical Analysis. When conducting correlation analyses by two independent groups of different sample sizes, typically, a comparison between the two correlations is examined. This is recommended when the correlations are conducted on the same variables by two different groups, and if both correlations are found to be statistically significant.

When the calculated P value is less than 0.05, the conclusion is that the two coefficients indeed differ significantly. Literature.

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.

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. Since this P-value is less than 0.05, it is concluded that the two correlation coefficients differ significantly.

This calculator will determine whether two correlation coefficients are significantly different from each other, given the two correlation coefficients and ...
