Hi, can anyone enlighten me on this -> Why is the 'choke' point or distribution point center and not elsewhere on the 'X' Axis? Why must it be in the center where the balls are falling from? It's like we assume every matter or natural system is always centered or ideally central to 'distribute'?

Well, then the curve would be shifted to the left or to the right, but it would retain its basic shape.

I think the reason is that binomial distribution (which approximates to normal distribution at a high number of balls) assumes that each event is independent of each other, meaning that each ball's chance of landing to the left and right should be 0.5. But events are only independent when he drops balls one by one. If he dumps them all in at once, the landing of one ball is going to depend on the landing of the previous ball because it likely hit that previous ball. Therefore, events are dependent and the binomial assumption no longer holds true.

Every slot gives a ball a 50/50 chance of going left or right, therefore the chances of it going right twice are 1/2 x 1/2 = 1/4. You keep going like that and you get a standard bell curve because the odds of them going to the middle are higher than them going to the sides. It's called a Galton Board

@@vagueeel823 No it s just physics, it is not binomial or normal distribution. The balls go down thanks to gravity and beacause they are launched from the center they accumulate in the center. If you launch them from the right of they will accumulate on the right, it will no more look like normal distribution.

@@iotala113 I...i mean yes it is physics, gravity is what's causing them to fall...just like everything else...and yes if you mess with the things that are controlling the movement of the balls, the things that CAUSE the 50/50 probability of them moving one way or another then they will collect in a different way. So i mean, youre not wrong? But what you said doesn't really answer the question. He was asking how it turned into a bell curve, from a statistics standpoint (which is honestly the more important factor here) the reason is because of what i said before.

It is not normal distribution neighter binomial distribution. It s just physics and the laws of physics are the same for each ball, they don't choose to go left or right at each pin, they just go down thanks to gravity. The balls are launch from the center of the board, so they accumulate at the center. If you launch them at the right, they will accumulate on the right, the same on the left. Because balls interact one with others and they are not perfect and pins are not pefect, balls go a little bit on the left, a little bit on the right, it's not 50/50. The first time I saw this board I was amazed, then I realize it was just a "trick"

Balls don't decide to go left or right at each pin BUT the chances to go left or right are the very likely to be the same (depending from the board execution quality); Balls also hit to each other in a overall random way.... At the end the ball SUM will be Normal distributed, with the center point aligned with release location.

if you launch the balls at the right, they will accumulate at the right because they will hit the right wall: giving you biased distribution. If there were more pegs to the right you would get the same shape.
