CHISQ.INV.RT
TheCHISQ.INV.RT
function returns the inverse of the righttailed probability of the chisquared distribution. It is commonly used in hypothesis testing and goodnessoffit analysis to determine whether an observed set of data is significantly different from a theoretical distribution. The function takes two arguments: the probability and the degrees of freedom.

Usage
Use the CHISQ.INV.RT
formula with the syntax shown below, it has 2 required parameters:
 probability (required):
The probability of the chisquared distribution in the righttail. Must be a decimal between 0 and 1, inclusive.  degrees_freedom (required):
The degrees of freedom of the chisquared distribution. Must be an integer greater than or equal to 1.
Examples
Here are a few example use cases that explain how to use theCHISQ.INV.RT
formula in Google Sheets.
Testing for independence in categorical data
In a chisquared test for independence, the CHISQ.INV.RT
function can be used to determine the critical value for rejecting the null hypothesis that two categorical variables are independent. For example, if we want to test whether there is a relationship between gender and voting preference, we can use the function to calculate the critical value for a given significance level and degrees of freedom.
Goodnessoffit test
The CHISQ.INV.RT
function can also be used in a goodnessoffit test to determine whether an observed set of data fits a theoretical distribution. For example, if we want to test whether a set of dice rolls follows a uniform distribution, we can use the function to calculate the critical value for a given significance level and degrees of freedom.

Google Sheets Formula:
Missing arguments
One or both of the required arguments are missing. Make sure to include both the probability and degrees_freedom arguments.
Invalid probability
The probability argument should be a decimal number between 0 and 1. Doublecheck that you have entered a valid probability value.
Invalid degrees of freedom
The degrees_freedom argument should be a positive integer. Doublecheck that you have entered a valid degrees of freedom value.
Incorrect order of arguments
Make sure to enter the probability argument first and the degrees_freedom argument second.
Related Formulas
The following functions are similar to CHISQ.INV.RT
or are often used with it in a formula:

CHISQ.INV
The CHISQ.INV function returns the inverse of the righttailed probability of the chisquared distribution. It is commonly used in hypothesis testing where the null hypothesis is that the observed data follows a chisquared distribution. The function returns the value of the chisquared random variable at which the cumulative distribution function equals the given probability. This function is useful for finding critical values after performing a chisquared test.

CHISQ.DIST.RT
The
CHISQ.DIST.RT
function returns the righttailed probability of the chisquared distribution. This function is commonly used in hypothesis testing and to calculate confidence intervals for the variance of a normal distribution. The chisquared distribution is often used in goodnessoffit tests and tests of independence in contingency tables. 
CHISQ.TEST
The
CHISQ.TEST
formula calculates the test for independence of two categorical ranges of data using the chisquared distribution. It returns the probability that any observed differences between the two ranges are due to chance. This formula is commonly used in hypothesis testing to determine whether there is a significant association between two variables. 
T.INV.2T
The
