The CHISQ.DIST.RT function returns the right-tailed probability of the chi-squared distribution.

• This function was introduced in Excel 2010 and so is not available in earlier versions.
• CHISQ.DIST.RT replaces the CHIDIST function included in earlier versions of Excel.

### Syntax

=CHISQ.DIST.RT(x,deg_freedom)

#### Arguments

Argument Description
x The value at which you want to evaluate the chi-square distribution – must be ≥ 0
deg_freedom The number of degrees of freedom – must be an integer between 1 and 1010
