**Syntax**. CHISQ.INV(*probability*,*degrees_freedom*)

**Definition**. This function returns the percentile of the left χ^{2}-distribution. If *probability* = CHISQ.DIST(*x*,...) then CHISQ.INV(*probability*,...) = *x*. Use this function to compare the observed results with the expected results in order to decide whether your original hypothesis is valid.

**Arguments**

### Note

If one of the arguments isn’t a numeric value, the CHISQ.INV() function returns the `#VALUE!`

error.

If *probability* is less than 0 or greater than 1, the CHISQ.INV() function returns the `#NUM!`

error. If *degrees_freedom* isn’t an integer, the decimal places are truncated. ...
