The textbook "Correlation Analysis in Excel" provides a comprehensive introduction to the fundamental methods of correlation analysis, which are significant for the study of general statistical theory. It is particularly aimed at students in the field of 36.03.02 - 'Animal Science'. The book explains how correlation analyses are used to assess the strength of the relationship between two or more variables within a statistical population. This method is especially useful for determining how the outcome variable changes when the influencing factors change, and for identifying the role of each individual factor. In agriculture, correlation analysis is widely applied in technical-economic analysis and in forecasting important production indicators such as animal productivity and labor productivity.
