- The light green represents the standard deviation and appears in the formula and on each side of the mean in the graph.
- Change the values of the statistics ( mean and standard deviation ) by clicking on the value on either side of the graph or through the input boxes at the bottom.
- Change the values of the
*x*and*z*scores by clicking on the values below the graph or by dragging the corresponding bars in the graph.
