This applet will help you experiment with the standard deviation and see how different standard deviations affect the spread of the data points from the mean. To use it, just adjust the value of the standard deviation by using the slider.

StandardDeviation = 0.25 02 O 1 Normal Distribution -3 -2 0 1 2 3 -1

Use the slider and set the standard deviation at 0.25. Look at the y-axis (vertical) and indicate where the apex (highest point) of the distribution curve is. When the mean is A and the standard deviation is B the apex of the normal distribution curve is C
