The term ‘correlation coefficient’ is based on the Pearson correlation test, which determines the strength and direction of the variables giving the output to the user in the range of -1 to 1.Ī value of -1 indicates a perfect negative correlation, while a value of +1 indicates a perfect positive correlation. The only difference between both functions is that the latter ‘sometimes’ showed rounding-off errors. The function is an upgrade to the PEARSON function, which returns the correlation coefficient based on the dataset of two variables.
The CORREL is categorized as a Statistical function that calculates the correlation coefficient for two sets of values from random populations.

In this article, we will see the syntax for the function, how to use it, and a couple of examples. This linear relationship is known as the correlation between the variables and can be calculated using this function. If there is a linear relationship between the two variables, it indicates that some correlation exists between the dataset. On the other hand, car B might only travel 50 miles for the same fuel.Ī correlation can be drawn between the amount of fuel and the mileage that the car travels and portray whether all the cars in the fleet show similar fuel consumption capabilities. If you buy 3 gallons of gas, car A can travel around 60 miles. So, for example, the mileage of the cars would vary for different models and depend on the fuel you buy from the gas station. In simple terms, it measures the strength of a linear relationship between two variables. The CORREL function in Excel calculates the correlation coefficient between the dataset of two variables.
