CORREL function

PRO

The CORREL function in Jspreadsheet Formulas Pro is a statistical tool used to determine the relationship between two sets of data. It returns a value called the correlation coefficient, which ranges from -1 to 1. A result of 1 indicates a strong positive relationship, -1 indicates a strong negative relationship, and 0 suggests no correlation. This can be useful in understanding how closely related your two data sets are.

Documentation

Returns the correlation coefficient between two data sets.

Syntax

CORREL(array1, array2)

Parameter	Description
`array1`	The first data set. An array or range of cells.
`array2`	A range or array containing the second set of numeric values, with the same length as array1.

Behavior

The 'CORREL' function is used to find the correlation coefficient between two data sets. Non-numeric values (text, booleans, blanks) are ignored entirely, providing it doesn't affect the correlation calculation. Boolean values are also treated as integers, with TRUE being 1 and FALSE being 0.

The function requires that the two data sets are of equal size. If they aren't, it will return an error. The function also requires that there are at least two pairs of data. If there is only one pair or none at all, it will also return an error.

Common Errors

Error	Description
#N/A	This error occurs when the two arrays have different lengths.
#DIV/0!	This error is displayed when there is less than two pairs of data in the arrays.

Best practices

Always ensure the two data sets are of the same size before using the 'CORREL' function to avoid errors.

Clean your data sets to remove or handle non-numeric values as they might affect your correlation results.

Use the 'CORREL' function to compare numerical variables. It's not suitable for comparing categorical variables.

Always interpret the result of the 'CORREL' function in the context of your data. A correlation of 0 doesn't necessarily mean there is no relationship, it could mean there is no linear relationship between your variables.

Usage

A few examples using the CORREL function.

CORREL(A2:A10, B2:B10) returns the correlation coefficient between the values in cells A2 through A10 and B2 through B10  
CORREL(C5:C25, D5:D25) returns the correlation coefficient between the values in cells C5 through C25 and D5 through D25  
CORREL(A1:A1000, B1:B1000) returns the correlation coefficient between the values in cells A1 through A1000 and B1 through B1000
