Product Description:
The Probability Demonstrator is an innovative normal distribution model that brings statistical concepts to life. Featuring 2800 metal beads and a cleverly designed obstacle system, this physics teaching aid visually demonstrates probability theory, making complex statistical principles tangible and interactive for students and educators.

Specification
Item Type: Probability Demonstrator
Material: ABS
Introduction:
Place a small round glass ball with a diameter slightly smaller than the distance between two nails at the entrance. As the ball descends, it rolls left or right with a probability of 1/2 after hitting a nail, and then touches the below layer of nail. Continue like this until rolling into the grid on the base plate. Countless small balls of the same size continuously fall from the entrance, and as long as there are a considerable number of balls, they will stack on the bottom plate to form a density function diagram that approximates a normal distribution (i.e. a symmetrical ancient bell shape, high in the middle and low at both ends), where n is the number of layers of nails.
