Embodiment 1

[0034] This embodiment provides a networked demonstration device for the principles of high-precision probability theory and mathematical statistics, which includes a receiving box 1, a rotating shaft 2 arranged at the center of the receiving box 1, and a number of partitions arranged in the receiving box 1. 3. The partition 3 evenly divides the receiving box 1 into a number of compartments 4, the receiving box 1 is provided with a receiving barrel 6 coaxial with the rotating shaft 2, on the receiving box 1 A rotary feeding mechanism 5 is provided, a discharging port 7 is provided at the lower end of the compartment 4, a counting mechanism 8 is provided on the discharging port 7 and the counting mechanism 8 is connected to a computer 9.

[0035] The demonstration of probability relies on the calculation of how much material (using light balls) enters the compartment. The rotating feeding mechanism regularly sends the balls into the receiving box through the receiving tube. The re...

Embodiment 2

[0040] This embodiment provides a high-precision networked demonstration device for the principles of probability theory and mathematical statistics, including a receiving box 1, a rotating shaft 2 arranged at the center of the receiving box 1, and a number of partitions arranged in the receiving box 1. 3. The partition 3 evenly divides the receiving box 1 into a number of compartments 4, the receiving box 1 is provided with a receiving barrel 6 coaxial with the rotating shaft 2, on the receiving box 1 A rotary feeding mechanism 5 is provided, a discharging port 7 is provided at the lower end of the compartment 4, a counting mechanism 8 is provided on the discharging port 7 and the counting mechanism 8 is connected to a computer 9.

[0041] The upper end of the rotating shaft 2 has a tapered structure, and the ball will hit the top of the rotating shaft when it falls from the receiving barrel. If the top of the rotating shaft is a flat structure, the small ball has a high probabil...

Abstract

The invention discloses a high-precision probability theory and mathematical statistical principle networked demonstration device which comprises a material receiving box, a rotary shaft arranged in the center in the material receiving box and a plurality of partition boards disposed in the material receiving box. The material receiving box is evenly divided into a plurality of partitions through the partition boards. A material receiving cylinder coaxial with the rotary shaft is arranged on the material receiving box. The material receiving box is provided with a rotary material supply mechanism. A discharge opening is formed in the lower end of each partition and provided with a counting mechanism which is connected with a computer. The computer is additionally arranged and configuration software is adopted, and a reasonable interface can be designed so that the probability demonstration process and a result can be displayed to more people, the requirement for information display during long-time running of the demonstration device can be met, the device is simple in structure, ingenious in design and capable of meeting requirements of the probability principle, and demonstration accuracy of the probability principle is high.

Description

Technical field [0001] The invention relates to the technical field of teaching aids for demonstration of probability theory and statistics, in particular to a networked demonstration device for the principles of probability theory and mathematical statistics with high precision. Background technique [0002] For students, class learning is the main way of learning, and teachers teach knowledge to students through classroom teaching. The course of Probability Theory accompanies students at all stages of learning, especially to the university level. Probability Theory involves more content and more knowledge points. The teacher’s explanation form has changed to electronic courseware tutoring, but it still hasn’t escaped from the boring explanation of knowledge points and the old-fashioned process of doing a lot of exercises. At present, there is no intuitive probability occurrence teaching aid to help students understand the principles of this course. Probability is a relatively ...
