X
A value at which to evaluate the function.
DegreesOfFreedom
The degrees of freedom for the distribution.
IsCumulative
TRUE to return the probability that a value is at most the value of the X parameter (the cumulative distribution function). FALSE to return the height of the distribution's curve at that value (the probability density function), which is useful for plotting the distribution but is not itself a probability.
Returns
A value for a chi-squared distribution.
Returns a value for a chi-squared distribution. The chi-squared distribution describes the sum of the squares of independent values drawn from the standard normal distribution, where the number of values is given by the DegreesOfFreedom parameter. It is used by chi-squared tests (see CHISQ.TEST).
Examples
Returns roughly 0.00021.
Returns roughly 0.16.
Returns roughly 0.53.
Returns roughly 0.74.
