抛硬币试验误差模型及分布规律

iming at the problem of large discrete results of coin tossing, this paper introduces concepts such as absolute error, relative error and frequency error, and establishes a mathematical model of coin tossing error using stochastic process analysis method. The statistical law of coin toss test error is given from two dimensions of space and time.The standard deviation of the absolute error of multiple coin tossing trials is directly proportional to the square root of the number of trials, and the relative error and frequency error of multiple coin tossing trials are inversely proportional to the square root of the number of trials. The absolute error of single group coin tossing test is directly proportional to the number of trials. Various error phenomena and problems in the coin tossing experiment can be explained theoretically.
