The CHISQ.INV.RT function in Excel is used to find the right-tailed inverse of the chi-square distribution. This function calculates the value of the chi-square variable that corresponds to a given probability level or significance level. By inputting a probability level and the degrees of freedom, the function returns the critical chi-square value for that probability level. This can be useful in statistical analysis, as it allows users to determine the critical value at which a chi-square test would reject the null hypothesis. The CHISQ.INV.RT function is a powerful tool for researchers and analysts working with chi-square distributions in Excel.
Returns the inverse of the right-tailed probability of the chi-squared distribution.
If probability = CHISQ.DIST.RT(x,…), then CHISQ.INV.RT(probability,…) = x. Use this function to compare observed results with expected ones in order to decide whether your original hypothesis is valid.
Syntax
CHISQ.INV.RT(probability,deg_freedom)
The CHISQ.INV.RT function syntax has the following arguments:
Probability Required. A probability associated with the chi-squared distribution.
Deg_freedom Required. The number of degrees of freedom.
Remarks
If either argument is nonnumeric, CHISQ.INV.RT returns the #VALUE! error value.
If probability < 0 or probability > 1, CHISQ.INV.RT returns the #NUM! error value.
If deg_freedom is not an integer, it is truncated.
If deg_freedom < 1, CHISQ.INV.RT returns the #NUM! error value.
Given a value for probability, CHISQ.INV.RT seeks that value x such that CHISQ.DIST.RT(x, deg_freedom) = probability. Thus, precision of CHISQ.INV.RT depends on precision of CHISQ.DIST.RT. CHISQ.INV.RT uses an iterative search technique. If the search has not converged after 64 iterations, the function returns the #N/A error value.
