The Galton board is to demonstrate the physical distribution that forms a Gaussian Curve or what is also called a normal distribution. The Gaussian Curve Distribution is a absolute continuous probability distribution with the mean at the peak of the curve. This statistical phenomenon is used to analyze distributions that tend to gather around the mean peak. This distribution is also known as the Bell Curve and is used a lot for evaluating class test distributions. The position of the pegs and the spacing of the pegs between each other are the direct variables that produce the Gaussian Distribution.<\/p>\n\n\n
