Learning outcomes
This course is designed to a) provide the students with tools to apply the products of the research in the horticultural sector and b) to correctly plan a research experiment and analyze to data a By the end of the course, the students will be able to: 1) understand the importance of the scientific method and its multiple-step process; 2) plan and perform simple and practical-oriented experiments in the field of horticultural research; 3) perform correctly the statistical analysis of biological observations; 4) communicate correctly the results of the scientific work.
