Natural variation produced a bell shaped curved, named the Standard Deviation.
The simulation below shows how successive throws of two dice will produce this curve. Use the settings shown and click on the roll dice buttons, 10, 100, 10000 to see the distribution curve without number throws. Press 100, reset then auto to see the curve building up with each throw of the dice. More throws will give a smoother curve. Press reset if needed
Click here to go to the simulator and click on the play button to throw the dice.
