ABOUT THE METHOD OF CORRELATION ANALYSIS OF EXPERIMENTAL DATA

Abstract

Mass data which learned as a result of scientific and practical experiments, are mostly probabilistic. For their processing are used methods of mathematical statistics which include correlation, regression, dispersion and other analysis. At current work are offered correlation and regressive analysis of the experimental result, on specific examples from agriculture. In practice, there is often a connection between variables in which the numerical value of one of them corresponds to several values of other. Such a relationship between signs (values) is called correlation (static connection). Rectilinear and curvilinear, direct and inverse correlation links are distinguished. In the work of experimental data is explored rectilinear correlation analysis of connection between yield and soil quality.
