In the work, using the methods of mathematical statistics, an analysis was made of the economic activity of the "Tourism" industry in terms of such indicators as: gross value added of the tourism industry, the share of gross value added of the tourism industry in the gross domestic product, the number of tour packages sold to the population, the number of travel agencies, the average number of employees and the average monthly accrued wages. workers' pay.

In the work, a two-factor mathematical model of deterministic factor analysis was studied by the method of chain substitutions, the method of absolute differences and the integral method. The comparison of the above methods is carried out on the example of solving a specific problem: analysis of the economic activity of the "Agriculture" branch of the economy.

In this work, a three-factor multiplicative mathematical model of deterministic factor analysis by the integral method is studied on the example of solving a specific problem of analyzing the economic activity of the manufacturing sector of the economy. As intermediate indicators, the average number of employees in the industry, the number of days worked by an employee per year and the average annual production of products by an employee of the industry were taken. The resulting indicator was the output of the industry.
