Specification Brand : RAPPRG BulletPoint1 : 【Professional】These statistical tools employ the use of gas molecules to elucidate the statistical regularity of velocity distributions. They serve as an educational instrument for the examination of models pertaining to stochastic phenomena, statistical distribution laws, and the rate of motion of gas molecules. BulletPoint2 : 【Principle】It can be observed that when beads are stacked in a bin, they appear to approximate a bell-shaped curve, as illustrated by the yellow line on the front of the Galton board. This Galton board, which is designed for hands-on use, offers the opportunity to gain insight into the order that can be found within the seemingly random chaos. BulletPoint3 : 【Process】It offers a visual representation of the statistical concept of the normal distribution. When the Galton plate is rotated along its axis, a stream of steel balls is initiated, which have an equal probability of bouncing left or right, and pass through several rows of nails to the point. BulletPoint4 : 【Application】:An incredible tool for physics lab equipment or as a lab decoration, which can improve the efficiency of physics experiment learning. Suitable for school lessons, educational displays and collections. It's a great addition to your lab supplies. and a unique for physics enthusiasts BulletPoint5 : 【High-Quality Service】As an honest international seller, we always do our best to ensure that our customers are satisfied with our products and services.
