Correlation-regression Analysis of the Relationship between the Volume of Sales of Goods and the use of Rotary Photo Tables for Their Presentation in Online Stores

Aims: The aim of this article was to determine the existence of a relationship between the volume of sales of goods by an online store and the use of rotary photo tables for the presentation of goods, using mathematical methods and models. 
Study Design: In order to determine the relationship between the volume of sales of goods at the online store and the use of rotary photo tables for the presentation of goods, economic and mathematical modeling was carried out on the base of the data of online store "Ukrasa". 
Place and Duration of Research: Russian Federation. 
Methodology: To achieve the goals, the research used such methods as analysis and synthesis, induction and deduction, comparison and grouping, methods of mathematical modeling (correlation-regression analysis). 
Results: On the basis of mathematical methods, it was established that there is a relationship between the volume of sales of goods by the online store and the number of goods that are presented with the help of photos and videos made with the use of turntables for photography. As a result of the research, it was established that 78,85% of the total change in the volume of sales of goods is explained by the change in the presentation of goods on the site with the help of rotary photo tables. 
Conclusion: The conducted research showed the importance of using rotary photo tables for presenting goods in online store. The economic interpretation of the parameters of the model shows that the increase in the number of goods presented with the help of photos and videos made with the use of rotary tables for photography will increase by one hundred units, then the volume of sales of goods will increase by 1661,9 thousand hryvnias.
