Course overview and goals
Biostatistics is the science that provides methodologies for how data are collected and analyzed in medical research, including basic, clinical, and epidemiological research. In this course, students will be able to understand the basic topics of biostatistics from the mathematical aspects. In addition, students will be able to understand how to prepare analysis data and how to interpret the results of statistical analysis through exercises using statistical software.
