Description: Of the errors made during each measurement, the most significant contribution is made by random errors. They appear arbitrarily, have an unpredictable character and significantly reduce measurement accuracy. Therefore, defining them is a paramount task. For this purpose, there are many methods based on the theory of their normal distribution. One of the main methods of ` combating ` random error is the method of ` randomization ` - conducting individual attempts on a pre-prepared plan, obtained by generating random numbers
