CHISQ.INV
Applies to: 
Calculated column
Calculated table
Measure
Visual calculation
Returns the inverse of the left-tailed probability of the chi-squared distribution.
The chi-squared distribution is commonly used to study variation in the percentage of something across samples, such as the fraction of the day people spend watching television.
Syntax
CHISQ.INV(probability,deg_freedom)
Parameters
| Term | Definition |
|---|---|
| Probability | A probability associated with the chi-squared distribution. |
| Deg_freedom | The number of degrees of freedom. |
Return value
Returns the inverse of the left-tailed probability of the chi-squared distribution.
Remarks
If argument is nonnumeric, CHISQ.INV returns the #VALUE! error value.
If probability < 0 or probability > 1, CHISQ.INV returns the #NUM! error value.
If deg_freedom is not an integer, it is rounded.
If deg_freedom < 0 or deg_freedom > 10^10, CHISQ.INV returns the #NUM! error value.
This function is not supported for use in DirectQuery mode when used in calculated columns or row-level security (RLS) rules.
