What are the differences among statistics, biostatistics and biometrics?
Statistics is a set of tools for collecting and summarizing data, and for using the data to draw inference from the population which it is supposed to represent.

Biostatistics usually refers to the application of statistics to the biological sciences, especially those relating to medical sciences. The statistical methods used in biostatistics do not differ substantially from those used in statistics. However, academic departments of biostatistics often have more faculty and students involved in applications of statistical methods to data compared to statistics departments. At many universities, the department of biostatistics is located in the medical school or a related college.

Biometrics is the application of mathematics and statistics to problems with a biological component, including problems in the agricultural, environmental and biological sciences as well as medical science. These include mathematical modeling, computational biology, applied mathematics and statistical methods. Academic departments of biometrics are often located in agricultural colleges, or colleges focusing on applied biology.
