Description Computes the correlation coefficient for two sets of numbers, paired up one-to-one.
Note The CORREL function is exactly the same as the PEARSON function. We provide both in order to be compatible with all the Microsoft Excel functions.
Syntax CORREL (array1, array2)
| Argument | Description |
|---|---|
| array1 and array2 | Two range references or array constants containing numeric values. Array1 and array2 must contain the same potential number of values.The function will return the error value #DIV/0! if array1 or array2 contains non-numeric data (text, logical values, or blank cells). |
Remarks The correlation coefficient is a number between -1 and 1 (inclusive) that measures the "relatedness" of the numbers in the samples. A coefficient of 1 indicates a direct relationship in which all points are linearly related on a line with positive slope. A coefficient of -1 indicates an inverse relationship in which a large value in the first argument pairs with a small value in the second argument. A coefficient of 0 indicates no relationship between the pairs of values, or complete randomness.
This function pairs up the numbers in the two ranges by moving left-to-right through each sequential row.
