A Pearson correlation coefficient of -0.54 indicates a moderate negative correlation between the two variables X and Y. This means that as the value of X increases, the value of Y tends to decrease, but not necessarily in a perfectly linear or predictable way. tozer trane moorestown

WebThe Pearson correlation coefficient [1] measures the linear relationship between two datasets. Like other correlation coefficients, this one varies between -1 and +1 with 0 implying no correlation. Correlations of -1 or +1 imply an exact linear relationship. Positive correlations imply that as x increases, so does y. WebCorrelation. The Pearson correlation coefficient, r, can take on values between -1 and 1. The further away r is from zero, the stronger the linear relationship between the two variables. The sign of r corresponds to the direction of the relationship. If r is positive, then as one variable increases, the other tends to increase.
