Synopsis
Score your highest in biostatisticsBiostatistics is a required course for students of medicine, epidemiology, forestry, agriculture, bioinformatics, and public health. In years past this course has been mainly a graduate-level requirement; however its application is growing and course offerings at the undergraduate level are exploding. Biostatistics For Dummies is an excellent resource for those taking a course, as well as for those in need of a handy reference to this complex material.
Biostatisticians—analysts of biological data—are charged with finding answers to some of the world's most pressing health questions: how safe or effective are drugs hitting the market today? What causes autism? What are the risk factors for cardiovascular disease? Are those risk factors different for men and women or different ethnic groups? Biostatistics For Dummies examines these and other questions associated with the study of biostatistics.
- Provides plain-English explanations of techniques and clinical examples to help
- Serves as an excellent course supplement for those struggling with the complexities of the biostatistics
- Tracks to a typical, introductory biostatistics course
Biostatistics For Dummies is an excellent resource for anyone looking to succeed in this difficult course.
