CHIDIST function

Returns the one-tailed probability of the chi-squared distribution. The γ2 distribution is associated with a γ2 test. Use the γ2 test to compare observed and expected values. For example, a genetic experiment might hypothesize that the next generation of plants will exhibit a certain set of colors. By comparing the observed results with the expected ones, you can decide whether your original hypothesis is valid.



X     is the value at which you want to evaluate the distribution.

Degrees_freedom     is the number of degrees of freedom.


  • If either argument is nonnumeric, CHIDIST returns the #VALUE! error value.

  • If x is negative, CHIDIST returns the #NUM! error value.

  • If degrees_freedom is not an integer, it is truncated.

  • If degrees_freedom < 1 or degrees_freedom ≥ 10^10, CHIDIST returns the #NUM! error value.

  • CHIDIST is calculated as CHIDIST = P(X>x), where X is a γ2 random variable.





Description (Result)




One-tailed probability of the chi-squared distribution, for the specified arguments (0.050001)
