Abstract. The topic "Statistical study of relationships between events" is one of the main directions of statistics, aimed at determining the interaction of various processes and events. This topic allows us to understand the cause-and-effect relationships between events by studying the quantitative relationship between them. Statistical methods, in particular, correlation and regression analysis, analysis of variance, and analysis of variation, assess the interrelationship of events and the strength of the relationship between them. This topic is of particular importance in linking theoretical knowledge with practice and is effectively used in various fields such as economics, social sciences, healthcare, and agriculture. Through these studies, it is possible to organize decision-making processes on a scientific basis, effectively use resources, and develop development strategies. Therefore, the study of statistical relationships is important in solving current problems in science and practice.
