Variations of the Normal Distribution

Move the sliders for the mean μ and the standard deviation σ to see how the normal distribution curve, i.e. the bell curve changes.
The values x = μ + σ and x = μ - σ are where the curvature of the bell curve changes from down to up. The bell curve curves downward on interval containing the mean, but it curves upward outside of this interval.
