The following plot is a Normal distribution as a function of 1) Mean , 2) standard deviation and 3) range of the independent variable. Point the mouse at one of the 3 sliders, left click and drag the slider either to the left or right to change its parameter value.  The normal plot below changes to reflect the new value.  Also next to each parameter slider is a + sign.  Point the mouse at the + sign and left click.  A control window for that parameter opens up and you can click the - or + sign in the control window to vary that parameter 1 step at a time.  The normal plot changes to reflect the new value of that parameter. Note, it may take a few seconds for the plot to update whenever a parameter is changed.
