Calculates the inverse of the left-tailed chi-squared distribution.

Sample Usage

CHISQ.INV(0.42, 2)



CHISQ.INV(probability, degrees_freedom)

  • probability - The probability associated with the left-tailed chi-squared distribution.

    • Must be greater than 0 and less than 1.

  • degrees_freedom - The number of degrees of freedom of the distribution.


  • degrees_freedom is truncated to an integer if a non-integer is provided.

  • degrees_freedom must be at least 1.

  • All arguments must be numeric.

Suppose you want to find the cutoff for the chi-squared statistic associated with a left-tailed probability of 0.95. With 4 degrees of freedom, you can consider any chi-squared statistic larger than 3.36 to be statistically significant.
