Calculate the one-tailed probability of the chi-squared distribution for a given Î³2 test.

`CHIDIST(x,degrees_freedom)`

- x - the value at which to evaluate the distribution
- deg_freedom - [OPTIONAL] the degrees of freedom

`=CHIDIST(A2,A3)`

For example, if we have data points A2 and A3, and we want to know the one-tailed probability of the chi-squared distribution for those two points, we can use the Sourcetable function. This will return the one-tailed probability of the chi-squared distribution for those two points.

The CHIDIST function is used to calculate the one-tailed probability of the chi-squared distribution for a Î³2 test. Note that the function does not work if degrees_freedom is less than 1 or is 10^10.

- The CHIDIST function calculates the probability of the chi-squared distribution and is used for a Î³2 test.
- The CHIDIST function returns the #VALUE! error value if either argument is not a number.
- The CHIDIST function truncates degrees_freedom if degrees_freedom is not an integer.

The CHIDIST function calculates the one-tailed probability of the chi-squared distribution.

The chi-squared distribution is used in a Î³2 test, which compares observed and expected values.

- The #VALUE! error is thrown if either argument is not numerical.
- The #NUM! error is thrown if x is negative.
- The degrees_freedom argument is truncated if it is not an integer.
