Area and the Normal Curve
The graph below is the same as the previous dynamic Normal Curve. The graph in blue is the Standard Normal Curve with mean of 0 and standard deviation of 1. The red curve changes shape with different values for the mean and standard deviation as you move the sliders to change the values. The AREA under the curves has been added here. Use the slider for the z score to find the area under the curve from - z to +z.
