Galton board Overview The Galton board demonstrates statistical concepts in motion, making abstract ideas like normal distribution and random walk visible and intuitive. The updated design features equal distances between the standard deviation lines and an equally sized brass bead that flows smoothly into the collection bin. Rotate the plate to create a stream of steel balls that bounce left or right with equal probability and form an approximation of the bell curve. Key benefits Clear visualization of normal distribution and probability in real time, useful for teaching and demonstrations. Improved plate layout with equal spacing between standard deviation lines for more accurate visual interpretation. Durable construction and simple operation let users focus on observation and learning rather than setup or maintenance. Compact, selfcontained device suitable for tabletop use in classrooms, labs, or exhibits. Specifications and components Name: Galton board Size: 44.8*31.6 cm Weight: 4Kg Material: plexiglass plate with a row of nails, Vshaped grooves, insert plates, notches, and other components to improve conversion rates Included component: equally sized brass bead that flows easily into the collection bin Product list: 1 Galton board How it works Rotate the Galton plate around its axis to start a stream of steel balls. As the beads fall, they collide with rows of nails and move left or right with equal probability at each collision. After passing through multiple rows, the beads collect in bins at the bottom, forming a distribution that approximates the normal curve. The device is also useful for illustrating statistical regularities such as velocity distributions of gas molecules and models of stochastic phenomena. Practical features Plexiglass construction for clear viewing of internal motion. Evenly spaced standard deviation markings for easy analysis. Vshaped grooves and insert plates designed to guide beads and increase consistency of results. Singlepiece unit that fits on a tabletop without additional setup. Use scenarios Classroom demonstration: Show students how random events accumulate into a predictable distribution in statistics, probability, and physics lessons. Laboratory teaching aid: Use in lab sessions to illustrate models of stochastic processes and the statistical interpretation of particle motion. Public exhibits and STEM outreach: Provide an interactive display for museums or events to engage audiences with handson exploration of probability and distribution. Care and precautions This instrument is made of organic glass. Handle with care to avoid collision or impact. After use, store the device in a cool, dry place to preserve clarity and component life. Operate by rotating the plate gently to ensure consistent bead flow and prevent damage. The Galton board offers a straightforward, durable way to explore statistical concepts through direct observation and handson interaction.
