Frequently Asked Questions
A normal distribution is a symmetric, bell-shaped probability distribution characterized by its mean (μ) and standard deviation (σ). It is widely used in statistics.
Enter the mean and standard deviation. Then either enter an X value to compute the probability P(X ≤ x) or enter a probability to find the corresponding quantile (x). Click Calculate.
The calculator requires only one of these inputs. If both are entered, an error message will appear. Please clear one field.
