Normal Distribution Calculator is a free online tool that displays the probability distribution for the given data set. CoolGyan’S online normal distribution calculator tool makes the calculation faster, and it displays the probability value in a fraction of seconds.

## How to Use the Normal Distribution Calculator?

The procedure to use the normal distribution calculator is as follows:

**Step 1:** Enter the mean, standard deviation, maximum and minimum value in the respective input field

**Step 2:** Now click the button “Calculate” to get the probability value

**Step 3:** Finally, the normal distribution of the given data set will be displayed in the new window

### What is Meant by Normal Distribution?

In Mathematics, the normal distribution is also known as the “Gaussian Distribution” is a probability distribution, where most of the data values tend to cluster around the mean. The normal distribution curve is also known as the bell-shaped curve. All the normal distributions are said to be symmetrical, but not all the symmetrical distributions are normal distributions. The distribution is said to be a normal distribution, where it has the following criteria:

- Symmetric about the centre
- Mean = Median = Mode
- 50% data values are less than mean and 50% data values are greater than mean
