◧ Arguments
| Argument | Type | Required | Description |
|---|---|---|---|
x |
Number | Required | The numeric value at which to evaluate the distribution |
deg_freedom |
Number | Required | An integer indicating the number of degrees of freedom. |
cumulative |
Logical | Required | A logical value that determines the form of the function. If cumulative is TRUE, T.DIST returns the cumulative distribution function; if FALSE, it returns the probability density function. |
▣ Examples
Student's left-tailed t-distribution for 60, returned as the cumulative distribution function, using 1 degree of freedom.
=T.DIST(60,1,TRUE)
Result:
0.99469533
Student's left-tailed t-distribution for 8, returned as the probability density function, using 3 degrees of freedom.
=T.DIST(8,3,FALSE)
Result:
0.00073691
§ Remarks
- If any argument is nonnumeric, T.DIST returns the #VALUE! error value.
- If deg_freedom < 1, T.DIST returns an error value. Deg_freedom needs to be at least 1.
✦ Tips
- If deg_freedom < 1, T.DIST returns an error value. Deg_freedom needs to be at least 1.
⚠ Common Errors
#VALUE!
If any argument is nonnumeric, T.DIST returns the #VALUE! error value.
Fix: مطمئن شوید هر سه آرگومان X و Deg_freedom و Cumulative عددی یا منطقی معتبر هستند و سلول ارجاعی متن نیست.
