Normal Distribution Calculator

Normal Distribution Calculator is a free online tool that displays the probability distribution for the given data set. BYJU’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
