Dynamic Normal Curve    (See also:  geogebra Area under Normal Curve     video Normal Distribution and the SNC) 

The graphs below represent the Normal Curve.
The graph in blue is the Standard Normal Curve with a mean,  μ = 0, and standard deviation, δ = 1.
To see how the shape of the normal curve changes with different values for the mean and standard deviation, move the sliders to change the values, and the shape of the normal curve in red will change accordingly.

What happens to the curve when the mean increases in value?

What happens to the curve when the standard deviation is less than 1?

What happens to the curve when the standard deviation is greater than 1?
