SFR 601 | Forest Mensuration Problems

This course is designed to provide graduate students with both a conceptual and practical understanding of how statistics are applied in forestry, with a particular focus on forest ecosystems, natural resources management, and ecosystem services. The course encompasses introductory statistical concepts and techniques, tailored to the specific needs of forest data analysis. It combines lectures, programming demonstrations in R, exercises, group discussions, and project development, offering a comprehensive approach to teaching applied statistics. Students will gain hands-on experience in data analysis, interpretation, and visualization. The course will cover various statistical methodologies, enabling students to select and apply the most appropriate techniques for different types of forest data and research questions. Eventually, students will be equipped with the necessary skills to effectively handle statistical challenges in forestry.
