![]() There are many formulas to calculate the correlation coefficient (all yielding the same result). You may use the linear regression calculator to visualize this relationship on a graph. ![]() Values close to -1 signal a strong negative relationship between the two variables. A value of 0 indicates that there is no relationship. One of the graphs demonstrates a positive correlation. The correlation coefficient, or Pearson product-moment correlation coefficient (PMCC) is a numerical value between -1 and 1 that expresses the strength of the linear relationship between two variables.When r is closer to 1 it indicates a strong positive relationship. The three scatter plot graphs below represent example of data with different correlation coefficients. Caution: The results for this test can be misleading unless you have made a scatter plot first to ensure your data roughly fits a straight line. For this particular data set, the correlation coefficient(r) is -0.1316. To clear the calculator and enter new data, press "Reset". The result will appear in the cell you selected in Step 2. The correlation coefficient will be displayed if the calculation is successful. Press the "Submit Data" button to perform the calculation. All x i values in the first line and all y i values in the second line:.You may enter data in one of the following two formats: This calculator can be used to calculate the sample correlation coefficient.Įnter the x,y values in the box above. You can use this Linear Regression Calculator to find out the equation of the regression line along with the linear correlation coefficient. Correlation Coefficient Calculator Instructions
