About this item
  • Dynamic Distribution Demonstration: The probability demonstration model can demonstrate the real time formation of the normal distribution curve. As the beads pass through the obstacles, complex statistical concept becomes vivid and intuitive.
  • Hands on Experiment: This physics teaching aid combines theoretical teaching with hands on experiment, allowing students to interact with probability through guided experimental activities.
  • Visualizing Probability Principle: Cleverly arranged hooks can โ€‹ falling beads to measurable statistical pattern. This physics demonstration model transforms abstract theoryโ€‹ into a tangible classroom experience.
  • Engaging Learning: The probability demonstrator combines engaging gameplay with rigorous scientific method, while systematically cultivating data analysis skills and experimental reasoning abilities to create unforgettable learning experiences.
  • Interactive Teaching: Teachers can use this board for immersive demonstration, allowing the trajectory of beads to activate students curiosity. Students can explore statistical patterns through visual observation and real time guidance from experts.
Product description

Product description 1. Visualizing Probability Principle: Cleverly arranged hooks can falling beads to measurable statistical pattern. This physics demonstration model transforms abstract theory into a tangible classroom experience. 2. Dynamic Distribution Demonstration: The probability demonstration model can demonstrate the real time formation of the normal distribution curve. As the beads pass through the obstacles, complex statistical concept becomes vivid and intuitive. 3. Hands on Experiment: This physics teaching aid combines theoretical teaching with hands on experiment, allowing students to interact with probability through guided experimental activities. 4. Interactive Teaching: Teachers can use this board for immersive demonstration, allowing the trajectory of beads to activate students curiosity. Students can explore statistical patterns through visual observation and real time guidance from experts. Spec: Item Type: Probability Demonstrator Material: ABS Introduction: Place a small round glass ball with a diameter slightly smaller than the distance between two nails at the entrance. As the ball descends, it rolls left or right with a probability of 1/2 after hitting a nail, and then touches the below layer of nail. Continue like this until rolling into the grid on the base plate. Countless small balls of the same size continuously fall from the entrance, and as long as there are a considerable number of balls, they will stack on the bottom plate to form a density function diagram that approximates a normal distribution (i.e. a symmetrical ancient bell shape, high in the middle and low at both ends), where n is the number of layers of nails. How to Use: Use directly. Package List: 1 x Probability Demonstrator 1 x User Manual Safety Warning this product has no safety hazard to users

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days โ€” so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
