§ Remarks
- If either argument is nonnumeric, T.INV returns the #VALUE! error value.
- If probability <= 0 or if probability > 1, T.INV returns the #NUM! error value.
- If deg_freedom is not an integer, it is truncated.
- If deg_freedom < 1, T.INV returns the #NUM! error value.
✦ Tips
- If deg_freedom is not an integer, it is truncated.
⚠ Common Errors
#VALUE!
If either argument is nonnumeric, T.INV returns the #VALUE! error value.
Fix: بررسی کنید Probability و Deg_freedom هر دو عددی باشند.
#NUM!
If probability <= 0 or if probability > 1, T.INV returns the #NUM! error value. If deg_freedom < 1, T.INV returns the #NUM! error value.
Fix: Correct the input value
