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)
The CHISQ.INV function syntax has the following arguments (argument: A value that provides information to an action, an event, a method, a property, a function, or a procedure.):
- Probability Required. A probability associated with the chi-squared distribution.
- Deg_freedom Required. The number of degrees of freedom.
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 truncated.
- If deg_freedom < 1 or deg_freedom > 10^10, CHISQ.INV returns the #NUM! error value.
