CORRELformula returns the correlation coefficient between two sets of data. This coefficient represents the strength of the linear relationship between the two sets of data, with values ranging from -1 (perfect negative correlation) to 1 (perfect positive correlation).

- Similar formulas to
CORREL formula with the syntax shown below, it has 2 required parameters:
- data_y (required):
An array or range containing the y-values of the data set.
- data_x (required):
An array or range containing the x-values of the data set.
ExamplesHere are a few example use cases that explain how to use the
CORRELformula in Google Sheets.
Finding the correlation between two sets of data
By using the
CORREL formula, you can easily calculate the correlation coefficient between two sets of data. This helps you determine if there is a strong or weak relationship between the two sets of data.
Evaluating the strength of a linear relationship
CORREL formula is frequently used in statistical analysis to evaluate the strength of a linear relationship between two sets of data. This helps determine if there is a significant correlation between the two sets of data.
Determining the direction of the relationship between two sets of data
The sign of the correlation coefficient returned by the
CORREL formula indicates the direction of the relationship between the two sets of data. A positive value indicates a positive relationship, while a negative value indicates a negative relationship.
CORRELnot working? Here are some common mistakes people make when using the
CORRELGoogle Sheets Formula:
Incorrect data range
One common mistake is selecting the wrong data range for either data_y or data_x. Make sure the ranges selected only include the data you want to analyze.
Not entering data ranges
Another mistake is not properly entering the data ranges for data_y and data_x. Make sure to use the correct syntax and separate the ranges with a comma.
Data ranges with different sizes
A mistake that can occur is when the data ranges for data_y and data_x have different sizes. Make sure the ranges are equal in size and have the same number of rows or columns.
The following functions are similar to
CORREL or are often used with it in a formula:
PEARSONfunction calculates the correlation coefficient between two sets of data points,
data_x. This coefficient indicates how closely related the two sets of data are. A high correlation coefficient indicates a strong positive correlation, while a low coefficient indicates a weak or negative correlation. This function is commonly used in statistical analysis and data visualization.
SLOPEformula calculates the slope of the linear regression line that best fits the input data. It is commonly used in statistics to analyze trends and predict future values based on past performance.
INTERCEPTfunction calculates the point where the line of best fit for a set of data intercepts the y-axis. This function is commonly used in regression analysis to find the constant b in the equation y=mx+b where m is the slope of the regression line.
