one decreases. Correlations don't prove causation, although it is possible that further tests will prove a causal relationship between the variables. The correlation coefficientRshows the strength of the relationship between the two variables, and whether it's a positive or a negative correlation. ...
It is important to note that the correlation coefficient measures the strength and direction of the linear relationship between two variables. The value of the correlation coefficient ranges from -1 to 1, where -1 indicates a perfect negative correlation, 0 indicates no correlation, and 1 indicates...
