Excel CHITEST Function

This post will guide you how to use the CHITEST function with syntax and examples in Microsoft excel.


The Excel CHITEST function returns the value from the chi-squared distribution for the statistic and the appropriate degrees of freedom. So you can the chi-square test to calculate the probability that the differences between two given date sets in Excel.

The CHITEST function is a build-in function in Microsoft Excel and it is categorized as a Statistical Function.

The CHITEST function is available in Excel 2016, Excel 2013, Excel 2010, Excel 2007, Excel 2003, Excel XP, Excel 2000, Excel 2011 for Mac.


The syntax of the CHITEST function is as below:

= CHITEST(actual_range, expected_range)

Where the CHITEST function arguments are:

  • Actual_range -This is a required argument. The actual range of data to test against expected range.
  • expected_range – This is a required argument.  The range of data that contains the ratio of the product of row totals and column totals to the grand total.


  • If actual_range and expected_range have a different number of data points, CHITEST returns the #N/A error value.
