Interpretation of correlation is often based on rules of thumb in which some boundary values are given to help decide whether correlation is non-important, weak, strong or very strong. This article shows that such rules of thumb may do more harm than good, and instead of supporting interpretati...

Correlation measures association, but doesn't show if x causes y or vice versa—or if the association is caused by a third factor. Correlation may be easiest to identify using a scatterplot, especially if the variables have a non-linear yet still strong correlation. ...
The correlation coefficient is always between -1 and +1. The closer the correlation is to +/-1, the closer to a perfect linear relationship. Here is how I tend to interpret correlations. -1.0 to -0.7 strong negative association.
A strong correlation doesn't indicate a causal relationship. Extreme Correlation Coefficients A correlation coefficient of zero or close to zero shows no meaningful relationship between variables.1A coefficient of -1.0 or +1.0 indicates a perfect correlation. A change in one variable perfectly predicts...
The Pearson correlation coefficient is frequently referred to as r. This is because r is the value it takes when using statistical notation. This type of coefficient is standardized, which means it must fall within certain bounds. This is in contrast to a value, such as the...
A correlation coefficient is the statistical measure that will tell us whether there is a relationship between our two variables of interest, and if there is one, how strong that relationship is. The value of the correlation coefficient, ρ (rho), ranges from -1 to +1. The closer to -1...
