لوحة جالتون المكتبية، نموذج العرض الاحتمالي، لوحة دالتون، أداة تجربة القانون الإحصائي الفعالة مع منحنى الجرس، لتعليم الفيزياء، مساعدة تعليمية في مختبر المدرسة
【Experimental Device】Vertical plate: with an opening at the top and multiple vertical collection slots at the bottom. The nails are arranged in a staggered manner to form a triangular layout. The ball is released from the top and eventually falls into a slot 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 on both sides gradually decreases, forming a bell curve
【Durable & Premium Construction】Crafted from high-quality acrylic and PP materials, this Dalton Board features sturdy nails, V-shaped grooves, and reinforced plates for long-term use
【Mathematical Principle】Binomial distribution: each layer of nails represents an independent experiment, and the probability of the ball going left/right each time it collides is p=0.5
【User-Friendly】Simple to operate with no setup required. Ideal for teachers to explain complex physics concepts visually, spark curiosity, and enhance learning
وصف
1. Statistics teaching: Demonstrate the formation of normal distribution to help students understand concepts such as probability distribution and the law of large numbers.
2. Probability experiment: Verify theoretical models through actual observation and enhance the understanding of randomness.
3. Popular science tool: Used in science museums or classrooms to demonstrate the deterministic laws of random processes.
