Application of correlation methods to the analysis of discrete measurement signals of a random nature

The theoretical part of the work discusses the correlation methods (scatter diagram, correlation scissors, Pearson's linear correlation coefficient), which should be used when determining the relationship between discrete random measurement signals. The practical part of the work presents an example of a correlation analysis (using graphical and analytical methods) of the actual measurement results (temperature, relative humidity and solar radiation intensity). On the basis of the obtained results, conclusions were formulated regarding the relationship between the analyzed signals, representing the above-mentioned physical quantities. © 2023 Wydawnictwo SIGMA-NOT.
