Calculates the inverse of the left-tailed chi-squared distribution.
probability- The probability associated with the left-tailed chi-squared distribution.
Must be greater than
0and less than
degrees_freedom- The number of degrees of freedom of the distribution.
degrees_freedomis truncated to an integer if a non-integer is provided.
degrees_freedommust be at least
All arguments must be numeric.
CHIDIST: Calculates the right-tailed chi-squared distribution, often used in hypothesis testing.
CHIINV: Calculates the inverse of the right-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.
F.INV: Calculates the inverse of the left-tailed F probability distribution. Also called the Fisher-Snedecor distribution or Snedecor’s F distribution.
T.INV: Calculates the negative inverse of the one-tailed TDIST function.
Suppose you want to find the cutoff for the chi-squared statistic associated with a left-tailed probability of
4 degrees of freedom, you can consider any chi-squared statistic larger than
3.36 to be statistically significant.
