ChiDist() returns the one-tailed probability of the chi2 distribution. The chi2 distribution is associated with a chi2 test.
Syntax:
CHIDIST(value, degrees_freedom)
Return data type: number
Arguments:
| Argument | Description | 
|---|---|
| value | The value at which you want to evaluate the distribution. The value must not be negative. | 
| degrees_freedom | A positive integer stating the number of degrees of freedom. | 
   This function is related 
 to the ChiInv function in the following way: 
If prob = CHIDIST(value,df), 
 then CHIINV(prob, df) = value
Limitations:
All arguments must be numeric, else NULL will be returned.
