Normal Distribution PDF Calculator
Calculates the normal distribution probability density function.
Formula: normdist(x0, mn, sd, 0)
See the Statistical Distributions Overview page for more statistical distribution calculators.
Example 1
| Value | Keystrokes | Display | Description |
|---|---|---|---|
| .5 | x | 0.5000 | Stores the x value. |
| 0 | μ | 0.0000 | Stores the mn (mean) value. |
| 1 | σ | 1.0000 | Stores the sd (standard deviation) value. |
| nrm | 0.3521 | Calculates the cumulative normal distribution |
Example 2
Calculate the standard deviation for a different value for example 1.
These keystrokes assume the values from example 1.
| Value | Keystrokes | Display | Description |
|---|---|---|---|
| .3 | nrm | 0.3000 | Stores the nrm value. |
| σ | 1.2232 | Calculates the sd value. |
