1. Introduction

Medical Statistics is a discipline that studies the collection, analysis and inference of digital data using the principle and method of probability theory and mathematical statistics, combining medical practice.

The object of medical research is the phenomenon of human health and disease, internal and external environment of human body and related organism is affected by many factors, many of which are unknown factors. Therefore, even if the things with the same nature, as to the same indicators, there are differences between individuals, this phenomenon is called variation.

The task of medical statistics is to reflect the characteristics and laws of the homogeneous things through the accidental phenomena.

(1). The biostatistics, the research objects include the whole biological world, also including human beings, so the research range is wider than medical statistics.
(2). Health statistics, focusing on the social aspects of medicine, such as population health statistics, health resource distribution and health service statistics, etc.
The three disciplines all use the theory and methods of mathematical statistic, the three have difference but no limit.
