Abstract

The invention discloses a statistical device for applied mathematics. The statistical device comprises a box body (1) and a base (2), the box body (1) is connected with the base (2) through a supporting column (3), a plurality of cams (4) capable of freely rotating are arranged on the inner bottom face of the box body (1), a plurality of ball outlet holes (5) are formed in the bottom of the box body (1), and a collecting pipe (6) is arranged under the ball outlet holes (5). The device is simple in structure, automatic and efficient experiments are achieved, artificial influences are avoided, and randomness is improved.

Description

technical field [0001] The invention belongs to the technical field of statistical devices, and in particular relates to a statistical device for applied mathematics. Background technique [0002] Probability, also known as probability, reflects the possibility of random events, that is, events that may or may not occur under the same conditions. Probability and statistics are an important research topic in advanced applied mathematics. For example, through probability and statistics, Calculate the proportion of commodity sampling inspection, so as to obtain a more accurate yield rate. When performing probability statistics, methods such as tossing coins are usually used, and people tend to cause large errors due to subjective consciousness and other reasons during statistics, which will affect the final result. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, the purpose of the present invention is to provide a statistic...
