CHIINVCalculates the inverse of the right-tailed chi-squared distribution.
probability – The probability associated with the right-tailed chi-squared distribution.
Must be greater than 0 and less than 1.
degrees_freedom – The number of degrees of freedom of the distribution.
degrees_freedom is truncated to an integer if a non-integer is provided.
degrees_freedom must be at least 1.
All arguments must be numeric.
CHIINV is synonymous with CHISQ.INV.RT.
CHIDIST: Calculates the right-tailed chi-squared distribution, often used in hypothesis testing.
CHISQ.INV: Calculates the inverse of the left-tailed chi-squared distribution.
CHISQ.INV.RT: Calculates the inverse of the right-tailed chi-squared distribution.
CHITEST: Returns the probability associated with a Pearson’s chi-squared test on the two ranges of data. Determines the likelihood that the observed categorical data is drawn from an expected distribution.
FINV: Calculates the inverse of the right-tailed F probability distribution. Also called the Fisher-Snedecor distribution or Snedecor’s F distribution.
TINV: Calculates the inverse of the two-tailed TDIST function.
Suppose you want to find the cutoff for the chi-squared statistic associated with a p-value of 0.05. With 4 degrees of freedom, you can consider any chi-squared statistic larger than 9.49 to be statistically significant.
