The correlation coefficient, often denoted as ( r ), ranges from -1 to +1. A value of +1 indicates a perfect positive linear relationship, where as one variable increases, the other also increases. A value of -1 indicates a perfect negative linear relationship, where one variable increases while the other decreases. A value of 0 suggests no linear correlation between the variables.
0% to 100%
When two variables are not related, the correlation coefficient is close to zero, indicating no linear relationship between them. This suggests that changes in one variable do not predict changes in the other. A correlation coefficient can range from -1 to 1, with values near zero demonstrating weak or no correlation.
The correlation coefficient is represented by the symbol ( r ) for Pearson's correlation coefficient, which measures the strength and direction of a linear relationship between two variables. For Spearman's rank correlation, it is denoted as ( \rho ) (rho). These coefficients range from -1 to 1, indicating the nature and strength of the correlation.
A correlation coefficient has a range of -1 to 1. Any number outside of this range has been incorrectly calculated. I note that is you meant to ask - Is r= -0.626 is a very strong correlation coefficient? then the answer No, this value is not a strong indicator that a linear relationship exists. Please see related link. The diagrams showing x-y graphs and the correlation coefficients is a good way to gain a "feel" of the coefficients and strength of relationships.
coefficient
the correlation coefficient range is -1 to +1
ɪf the regresion coefficient is the coefficient of determination, then it's range is between 0 or 1. ɪf the regression coefficient is the correaltion coefficient (which i think it is) the it must lie between -1 or 1.
You can describe if there's any obvious correlation (like a positive or negative correlation), apparent outliers, and the corrlation coefficient, which is the "r" on your calculator when you do a regression model. The closer "r" is to either -1 or 1, the stronger that correlation is.
