How to Use This Normal Distribution Calculator
Using the Normal Distribution Calculator is easy. Just follow these steps:
- Enter the mean (average) of your data.
- Enter the standard deviation to show how spread out your data is.
- Enter the value you want to find the probability for.
- Click Calculate and get your result instantly.
No complicated forms or extra steps. Everything you need is right above.
How the Calculation Works
This calculator uses the normal distribution formula, but you don’t need to worry about the math. In simple terms:
- The mean is the centre of your data.
- The standard deviation tells you how spread out the data is.
- The calculator finds how likely a number is to appear compared to the average.
Example:
If the average test score is 70 with a standard deviation of 10, you can find the probability of a student scoring 80. Enter 70 as the mean, 10 as the standard deviation, and 80 as the value. The calculator will give the probability instantly.
Why People Use This Normal Distribution Calculator
