Biostatistics is a branch of statistics that focuses on the design and analysis of data from biological and health sciences. It involves the use of statistical methods to make inferences and draw conclusions from biological and medical data, such as clinical trials, public health studies, genetics research, and epidemiological studies. Biostatisticians work to develop and apply statistical techniques to help understand complex biological processes, identify risk factors for diseases, evaluate the effectiveness of treatments, and make informed decisions in healthcare and public health policy. In essence, biostatistics aims to provide valuable insights and contribute to advancements in the field of biology and medicine through the rigorous application of statistical methods.
