Learning outcomes
At the end of the course, the student will know the statistical techniques applied to agricultural biotechnology. In addition to acquiring basic knowledge of descriptive statistics, the student will understand the logic of statistical inference and will be able to apply the most common statistical tests in research and the profession of an agricultural biotechnologist. The student will also be able to perform statistical analyses with dedicated software and interpret the output in the context of the analyzed phenomenon or experiment.
