CHIINV: Excel Formulae Explained

How do you use CHIINV in Excel?

The CHIINV function in Excel is used to calculate the inverse of the chi-squared distribution. The function takes one argument, which is the number of degrees of freedom. The inverse of the chi-squared distribution is used to calculate the p-value for a chi-squared statistic.

What is the syntax of CHIINV in Excel?

The syntax of the CHIINV function in Excel is as follows: =CHIINV(x,deg_freedom) The function takes a single argument, x, which is the value you want to calculate the inverse chi-squared statistic for. The second argument, deg_freedom, is the number of degrees of freedom.

What is an example of how to use CHIINV in Excel?

The CHIINV function is used in Excel to calculate the inverse of the chi-squared distribution. The function takes two arguments, the first being the number of degrees of freedom and the second being the chi-squared value.
