The correlation coefficient = 6(20,485) – (247 × 486) / [√[[6(11,409) – (2472)] × [6(40,022) – 4862]]] = 0.5298 The range of the correlation coefficient is from -1 to 1. Our result is 0.5298 or 52.98%, wh
How do I calculate the correlation coefficient? 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 ...

Definition:The correlation coefficient, also commonly known as Pearson correlation, is a statistical measure of the dependence or association of two numbers. When two sets of numbers move in the same direction at the same time, they are said to have a positive correlation. When one series of n...
Correlation coefficient measures the degree to which two variables move together. Its value ranges between -1 and 1. -1 indicates perfectly negative relationship, 1 shows a perfectly positive relationship and zero means there is no linear relationship be
The approximation of experimental data using the Microsoft Office Excel software was considered; it eliminated the complicated and laborious calculation of the coefficients of approximation equation and the correlation coefficient. It was found that, for the studied test systems, the detection limit was ...

R2 = (Correlation Coefficient)2 Adjusted R Squared = 1 – [((1 – R2) * (n – 1)) / (n – k – 1)] Where: n–Number of points in your data set. k–Number of independent variables in the model, excluding the constant
This function takes two vectors as arguments and it returns the correlation coefficient between them. Another way to calculate R-squared is to use the “lm” function in R. This function fits a linear model to a set of data and returns the coefficient of determination for that model. ...
