◧ Arguments
| Argument | Type | Required | Description |
|---|---|---|---|

Number | Required | The standard deviation of the distribution. |
▣ Examples
▦ Data
| Cell | Value | Description |
|---|---|---|
A2 |
0.908789 | Probability corresponding to the normal distribution |
A3 |
40 | Arithmetic mean of the distribution |
A4 |
1.5 | Standard deviation of the distribution |
A5 |
0.908789 | Probability corresponding to the normal distribution |
A6 |
40 | Arithmetic mean of the distribution |
A7 |
1.5 | Standard deviation of the distribution |
Inverse of the normal cumulative distribution for the terms above (42)
=NORM.INV(A2,A3,A4)
Result:
42.000002
§ Remarks
- If any argument is nonnumeric, NORM.INV returns the #VALUE! error value.
- If probability <= 0 or if probability >= 1, NORM.INV returns the #NUM! error value.
- If standard_dev ≤ 0, NORM.INV returns the #NUM! error value.
- If mean = 0 and standard_dev = 1, NORM.INV uses the standard normal distribution (see NORMS.INV).
- Given a value for probability, NORM.INV seeks that value x such that NORM.DIST(x, mean, standard_dev, TRUE) = probability. Thus, precision of NORM.INV depends on precision of NORM.DIST.
✦ Tips
- If mean = 0 and standard_dev = 1, NORM.INV uses the standard normal distribution (see NORMS.INV).
- Given a value for probability, NORM.INV seeks that value x such that NORM.DIST(x, mean, standard_dev, TRUE) = probability. Thus, precision of NORM.INV depends on precision of NORM.DIST.
⚠ Common Errors
#VALUE!
If any argument is nonnumeric, NORM.INV returns the #VALUE! error value.
Fix: همه آرگومانها را بهصورت عدد وارد کنید.
#NUM!
If probability <= 0 or if probability >= 1, NORM.INV returns the #NUM! error value. If standard_dev ≤ 0, NORM.INV returns the #NUM! error value.
Fix: Correct the input value
