CHISQ.INV function

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.
