3.4. Based on this figure, we can see that weak, moderate, and robust correlations can occur in both positive and negative values of the R. If the correlation coefficient between actual values and estimated values is zero, it indicates that these two variables (i.e., actual values and ...

Correlation Matrix:The correlation matrix is a table that represents the values of correlation coefficients for different variables. It shows a numeric value of the correlation coefficient for all the possible combinations of the variables. It is used when determining the relationship between more than ...
the correlation coefficient reveals relationships along the following ordinal scale: little to any correlation (0.00≤∣r∣<0.30), low correlation (0.30≤∣r∣≤0.49), moderate correlation (0.50≤∣r∣≤0.69), high correlation (0.70≤∣r∣≤0.89), and very high correlation (0.90≤∣r∣≤1.00)...

Cases with the modulus of the correlation coefficient, ǀrǀ, 0.30–0.49, 0.50–0.69, and 0.70–0.99, respectively, were classified as those of weak, moderate, and strong correlation between the amplitudes. At ǀrǀ < 0.30, correlations were considered insignificant. Cases of significant ...

Likely most problematic is that Cramer's V has no meaningful interpretation; a large coefficient does not necessarily indicate a strong association, and likewise, a small coefficient does not necessarily indicate a weak association. As a result, several alternatives to Cramer's V have been proposed...
