The Excel Chisq.Dist.Rt function calculates the right-tailed probability of the Chi-Square Distribution
The function is new in Excel 2010 and so is not available in earlier versions of Excel. However, the Chisq.Dist.Rt function is simply an updated version of the Chidist function that is available in earlier versions of Excel.
The syntax of the Chisq.Dist.Rt function is:
where the function arguments are:
|x||-||The value at which you want to evaluate the chi-square distribution (must be ≥ 0).|
|degrees_freedom||-||(If the supplied value is a decimal, this is truncated to an integer).|
The above chart on the right shows the right-tailed chi-square distribution, with 1, 2 and 3 degrees of freedom.
Further examples of the Excel Chisq.Dist.Rt function are provided on the Microsoft Office website.
If you get an error from the Excel Chisq.Dist.Rt function this is likely to be one of the following:
|#VALUE!||-||Occurs if either of the supplied arguments are non-numeric.|
