Galton Board Desk Toy, Dalton Board bability Demonstration Model Effective Statistical Law Experiment Tool with Bell Curve for Physical School Laboratory Teaching
Statistical Tools: Galton board is a fessional tool for analyzing the statistical distribution of molecular velocity and studying the model of random phenomena. It is used as a teaching tool to study the model of random phenomena, the law of statistical distribution and to explain the rate of motion of gas molecules.
Vertical plate: There are openings at the upper end, and multiple vertical collection grooves are arranged at the lower end. Multi-layer nails: The nails are staggered, and each layer has one more nail than the upper layer to form a triangular layout. Small ball: Released from the top, collides with the nails during the falling cess, and finally falls into a groove at the bottom.
Experimental phenomenon: The path of a single ball is random and may fall into any slot. After releasing a large number of balls, the middle slot gathers the most, and the number of both sides gradually decreases, forming a bell curve.
Binomial distribution: Each layer of nails represents an independent test, and each collision of the ball has a bability of going left/right p = 0.5.
Material: Crafted from pp material, this dalton board ensures durability and longevity, making it suitable for repeated use in classrooms or educational demonstrations
