Thus, the interpretation of the correlation coefficient is very simple: values close to 1 indicate strongly positive linear relationships, values close to −1 indicate strongly negative linear relationships, and values close to zero indicate that the variables have little or no linear relationship. ...
Correlation coefficient-相关系数 The Pearsonian (product moment) correlation coefficient measures how strong the connection is between the two variables. When correlation is strong, the estimated line of best fit should be more reliable. Interpretation: ...
Correlation Coefficient Interpretation In the correlation coefficient, r falls in the range of +1.0 to -1.0, depending on the strength of the relationship between the two variables. An r of 0 indicates that there is no relationship between the two variables. An r of +1.0 describes a positive...
The correlation coefficient formula is: r = (n*sumXY - sumX*sum Y)/sqrt{(n*sumX^2 - (sumX)^2)*(n*sumY^2 - (sumY^2))}.The terms in that formula are: n = the number of data points, sumXY is the sum of the product of the x-value and y-value for each point in the ...

Interpretation The correlation coefficient ranges from ?1 to 1. A value of 1 implies that a linear equation describes the relationship between X and Y perfectly, with all data points lying on a line for which Y increases as X increases. A value of ?1 implies that all data points lie on...
Correlation, in the finance and investment industries, is a statistic that measures the degree to which two securities move in relation to each other. Correlations are used in advancedportfolio management, computed as thecorrelation coefficient, which has a value that must fall between -1.0 and +...
