Critical values for correlation coefficients
www.mun.ca › biology › scarrCritical values for correlation coefficients. Critical Values for thecorrelation coefficient r. Consult the table for the critical valueof v= (n - 2)degrees of freedom, where n= number of paired observations. For example, with n= 28, v= 28 - 2 = 26, and the critical value is 0.374 ata= 0.05 significance level.
Critical Correlation Calculator - MathCracker.com
mathcracker.com › critical-correlation-calculatorand this value of \(r_c\) is the so called critical correlation value used to assess the significance of the sample correlation coefficient \(r\). These critical correlation values are usually found in specific tables. Observe that this calculator applies for Pearson's correlation, so you would need to use a Spearman’s Critical Correlation Calculator if you are dealing with Spearman's correlation coefficient.
