The use of statistical methods to analyze data related to living organisms and health.
Biostatistics is essential for understanding the effectiveness of new medical treatments.
Biostatistics is formed from "bio-" (from Greek "bios", meaning life) and "statistics" (from Latin "statisticus", meaning of state or political). The word refers to the application of statistical methods to biological and health-related processes, essentially the study of life through statistics.
Think of 'bio-' meaning life and 'statistics' relating to data — biostatistics is all about using data to understand life.
