§ Remarks
- If argument is nonnumeric, CHISQ.INV returns the #VALUE! error value.
- If probability < 0 or probability > 1, CHISQ.INV returns the #NUM! error value.
- If deg_freedom is not an integer, it is truncated.
- If deg_freedom < 1 or deg_freedom > 10^10, CHISQ.INV returns the #NUM! error value.
✦ Tips
- If deg_freedom is not an integer, it is truncated.
⚠ Common Errors
#VALUE!
If argument is nonnumeric, CHISQ.INV returns the #VALUE! error value.
Fix: برای هر دو آرگومان مقدار عددی وارد کنید.
#NUM!
If probability < 0 or probability > 1, CHISQ.INV returns the #NUM! error value. If deg_freedom < 1 or deg_freedom > 10^10, CHISQ.INV returns the #NUM! error value.
Fix: Correct the input value
