See full list on howtoexcel.org. Excel calculates the Pearson correlation coefficient for your data range and displays it in the cell. Calculate P-Value 6. Click a different cell that you want to use to calculate the p-value that is associated with your correlation. Finding a P-value in Excel that corresponds to the correlation coefficient (r) can be accomplished using a formula and a built-in function. From Excel 2003 onward, the same process can be used to find the correlation coefficient and to convert this into a P-value for significance tests. P Value from Pearson Correlation Coefficient Calculator. Pearson Correlation Coefficient, also known as Pearson's R or PCC is a measure of linear correlation between two variables X and Y giving values from -1 to +1. P value is used for testing statistical hypothesis. Use this calculator to find the p value based on the PCC. While in excel, there isn’t a formula that gives a direct value of correlation’s associated P-Value. So we have to get P-Value from correlation, correlation is r for P-Value as we have discussed before, to find P-Valuepvalue we have to find after getting correlation for the given values.

The Pearson product-moment correlation coefficient is a statistical measurement of the correlation (linear association) between two sets of values.

The Pearson product-moment correlation coefficient for two sets of values, x and y, is given by the formula:

where x and y are the sample means of the two arrays of values.

If the value of r is close to +1, this indicates a strong positive correlation, and if r is close to -1, this indicates a strong negative correlation.

Further information on the Pearson Product-Moment Correlation Coefficient is provided on Wikipedia

Function Description

The Excel Pearson function calculates the Pearson Product-Moment Correlation Coefficient for two sets of values.

How Do You Calculate Pearson Correlation Coefficient In Excel

The syntax of the function is:

Where array1 is a set of independent variables and array2 is a set of dependent variables. These two arrays should have equal length.

Note that the Pearson function ignores text values and logical values that are supplied as part of an array.

Excel Pearson Function vs. Excel Correl Function

The Excel Pearson function performs the same calculation as the Excel Correl Function. However, in earlier versions of Excel (earlier than Excel 2003), the Pearson function may exhibit some rounding errors.

Therefore, if you are using an earlier version of Excel, you should use the Correl function in preference to the Pearson function. In more recent versions of Excel, both functions should give the same results.

Pearson Function Example

A	B
1	x	y
2	1	10.11
3	2	22.90
3	2	27.61
4	3	27.61
5	4	11.15
6	5	31.08
7	6	37.90
8	7	33.49
9	8	21.05
10	9	27.01

17	16	36.18
18	17	49.77
19	18	55.66
20	19	63.83
21	20	63.60

Columns A and B of the above spreadsheet on the right contain two arrays of values. These are displayed in the chart below:

The Pearson Product-Moment Correlation Coefficient of these values can be calculated using the Excel Pearson function, as follows:

This gives the result 0.870035104, indicating a strong positive correlation between the two sets of values.

A useful table for on interpreting the significance of the Pearson Product-Moment Correlation Coefficient is provided on the University of Connecticut website

Pearson Function Errors

How To Calculate P-value From Pearson Correlation

If you get an error from your Excel Pearson function this is likely to be one of the following:

#N/A	-	Occurs if the supplied array arguments have different lengths.
#DIV/0!	-	Occurs if either of the supplied array arguments is empty or if the standard deviation of their values is equal to zero.
