CHISQ.INV()

Syntax. CHISQ.INV(probability,degrees_freedom)

Definition. This function returns the percentile of the left χ2-distribution. If probability = CHISQ.DIST(x,...) then CHISQ.INV(probability,...) = x. Use this function to compare the observed results with the expected results in order to decide whether your original hypothesis is valid.

Arguments

  • probability (required). A probability associated with the χ2-distribution

  • degrees_freedom (required). The number of degrees of freedom

Note

If one of the arguments isn’t a numeric value, the CHISQ.INV() function returns the #VALUE! error.

If probability is less than 0 or greater than 1, the CHISQ.INV() function returns the #NUM! error. If degrees_freedom isn’t an integer, the decimal places are truncated. ...
