CHISQ.INV

  • Article

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.
