✦ Tips
- This function has been replaced with one or more new functions that may provide improved accuracy and whose names better reflect their usage. Although this function is still available for backward compatibility, you should consider using the new functions from now on, because this function may not be available in future versions of Excel. For more information about the new functions, see T.INV.2T function or T.INV function.
- If deg_freedom is not an integer, it is truncated.
- TINV returns that value t, such that P(|X| > t) = probability where X is a random variable that follows the t-distribution and P(|X| > t) = P(X < -t or X > t).
⚠ Common Errors
#VALUE!
If either argument is nonnumeric, TINV returns the #VALUE! error value.
Fix: بررسی کنید Probability و Deg_freedom هر دو عددی باشند.
#NUM!
If probability <= 0 or if probability > 1, TINV returns the #NUM! error value. If deg_freedom < 1, TINV returns the #NUM! error value.
Fix: Between 0 and 1
#N/A
If the search has not converged after 100 iterations, the function returns the #N/A error value.
Fix: مقادیر ورودی را بررسی کنید و با مقادیر معتبر دوباره امتحان کنید؛ در صورت تکرار، احتمال یا درجات آزادی را کمی تغییر دهید.
