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.

biomechanics 中文是生物力学。
生物力学是研究与生物体有关的力学问题，其主要内容是利用力学的基本原理，结合生理学、医学和生物学来研究生物体，特别是人体的功能、生长、消亡及运动的规律。

Definition of Biomechanics

A. Broad definition: the application of the principles and technology of the physics and mechanical engineering science to the problems in the context of the living system, which is a multidisciplinary study including
a. Physical properties of biological materials
b. Biological signals and their measurements
c. Biomechanical modeling and simulation
d. Applications of biomechanics

B. Limited definition (for musculoskeletal system only): the science that examines forces acting upon and within a biological structure and effects produced by such forces (Hay, 1973)
1. forces on a system: external forces or internal forces
2. effects of forces:
a. movements of segments of interest
b. deformation of biological materials
c. biological changes in the tissue(s) on which they act

C. Knowledge needed in biomechanical studies
1.mathematics
2.physics
3.mechanics
a.rigid body mechanics: statics and dynamics
b.mechanics of deformable materials
c.fluid mechanics
4.biology and medicine
5.neurophysiology
6.behavior science
