# WorksheetFunction.ChiSq_Dist_RT (Excel)

Returns the right-tailed probability of the chi-squared distribution.

The χ2 distribution is associated with an χ2 test. Use the χ2 test to compare observed and expected values. For example, a genetic experiment might hypothesize that the next generation of plants will exhibit a certain set of colors. By comparing the observed results with the expected ones, you can decide whether your original hypothesis is valid. If either argument is nonnumeric, ChiSq_Dist_RT generates an error. If x is negative, ChiSq_Dist_RT generates an error. If degrees_freedom is not an integer, it is truncated. If degrees_freedom < 1 or degrees_freedom > 10^10, ChiSq_Dist_RT generates an error. ChiSq_Dist_RT is calculated as ChiSq_Dist_RT = P(X>x), where X is an χ2 random variable.

**ChiSq_Dist_RT** (Arg1, Arg2)

```
Dim dblArg1 As Double: dblArg1 =
Dim dblArg2 As Double: dblArg2 =
Dim dblChiSq_Dist_RT As Double
dblChiSq_Dist_RT = WorksheetFunction.ChiSq_Dist_RT(Arg1:=dblArg1, Arg2:=dblArg2)
```

## Arguments

Arg1, Arg2Arg1 (Double) - The value at which you want to evaluate the distribution.

Arg2 (Double) - The number of degrees of freedom.
