Returns the right-tailed probability of the chi-squared distribution. The χ2 distribution is associated with a χ2 test. Use the χ2 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.
The CHIDIST function syntax has the following arguments:
X Required. The value at which you want to evaluate the distribution.
Deg_freedom Required. 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 deg_freedom is not an integer, it is truncated.
If deg_freedom < 1 or deg_freedom > 10^10, CHIDIST returns the #NUM! error value.
CHIDIST is calculated as CHIDIST = P(X>x), where X is a χ2 random variable.
