Another function that can be used to calculate correlation coefficient in Excel is the SPEARMAN function. This function calculates the Spearman’s rank correlation coefficient, which is a non-parametric measure of correlation. It is used when the data sets being compared are not normally distributed...

In this lesson, we have determined thecorrelation coefficientbetween wins and losses and coffee sales. The correlation coefficient shows the strength of a relationship between variables. It is NOT causation! In Excel, you can use theCORRELfunction to calculate the coefficient or use an Add-in, th...
The correlation coefficient, or r, always falls between -1 and 1 and assesses the linear relationship between two sets of data points such as x and y. You can calculate the correlation coefficient by dividing the sample corrected sum, or S, of squares for (x times y) by the square root...
In this tutorial, I will show you two really easy ways to calculate correlation coefficient in Excel. There is already a built-in function to do this, and you can also use the Data Analysis Toolpak. So let’s get started! This Tutorial Covers: What is the Correlation Coefficient? Calcu...
There are many questions to ask when looking at a scatterplot. One of the most common is wondering how well a straight line approximates the data. To help answer this, there is a descriptive statistic called the correlation coefficient. We will see how to calculate this statistic. ...
