CHIDIST(x,degrees_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 γ2 test. Note that the function does not work if degrees_freedom is less than 1 or is 10^10.
