Let’s calculate.

Use the Calculate button to see your result.

Review the method below for assumptions and conventions.

How to use this tool

  1. Enter observed value, mean, standard deviation.
  2. Select Calculate to view the result.
  3. Check the method and assumptions below before using the result.

The method, explained

Density = exp[−(x − μ)²/(2σ²)]/(σ√(2π)).

A WORKED EXAMPLE

Using observed value = 0, mean = 0, standard deviation = 1, the result is 0.39894228. Change these example inputs to match your task; use the method above to check each step.

What to keep in mind

Density is not the probability of a single exact value and may exceed 1. A descriptive or probability calculation under the stated assumptions. Check the sample design and model before interpreting results.

Common questions
