Fundamentals of scientific research in gardening. Textbook

The textbook presents information about the scales of the assessment of signs, methods of their unification, statistical sampling parameters and methods for assessing their reliability. Algorithms for determining sufficient volumes of samples in the study of medium, the difference between the average, shares, the difference between shares, calculating the correlation coefficients are discussed. The basics of using non -parametric analysis methods are set out to assess the representativeness and uniformity of samples. The calculation algorithms and directions of using the Pieron criterion are discussed. The restrictions and algorithms of correlation, regression and dispersion analyzes are presented. The basic principles of numerical taxonomy, the algorithms of weightless and weight classifications, hierarchical and non -iligrachic methods of highlighting clusters are presented. The final part of the textbook contains information about the features of planning experiments with garden plants, the implementation of the research plan, the structure of scientific research, its design, and the requirements for the presentation of scientific work. There is also a list of recommended literature, glossary, formulas for calculating statistical parameters, statistical tables.
The textbook is addressed to bachelors and master in the direction of "gardening", as well as graduate students and researchers in the field of agriculture and biology
