About this book
The Handbook of Statistics for Teaching and Research in Plant and Crop Science presents the fundamental concepts of important statistical methods and experimental designs to the students and researchers who need to apply them to their own specific problems. This comprehensive handbook takes what can be the difficult and confusing topics of statistics and experimental design and explains them in understandable and accessible terms. This title provides an essential reference guide for researchers and professionals on the latest techniques involved in the latest thinking on crop science.
