__5.Definition of Statistics:__Statistics like many other sciences is a developing discipline. It is not nothing static. It has gradually developed during last few centuries. In different times, it has been defined in different manners. Some definitions of the past look very strange today but those definitions had their place in their own time. Defining a subject has always been difficult task. A good definition of today may be discarded in future. It is difficult to define statistics. Some of the definitions are reproduced here:

**(i)**The kings and rulers in the ancient times were interested in their manpower. They conducted census of population to get information about their population. They used information to calculate their strength and ability for wars. In those days statistics was defined as

**“**

*the science of kings, political and science of statecraft*”**(ii)**A.L. Bowley defined statistics as

*“statistics is the science of counting”***(iii)**A.L. Bowley has also defined as

**“**

*science of averages*”**(iv)**Prof: Boddington has defined statistics as

*“science of estimate and probabilities”***(v)**A definition due to W.I. King is

**. This definition is close to the modern statistics. But it does not cover the entire scope of modern statistics. Secrist has given a detailed definition of statistics in plural sense. His definition is given on the previous. He has not given any importance to statistics in singular sense. Statistics both in the singular and the plural sense has been combined in the following definition which is accepted as the modern definition of statistics.**

*“the science of statistics is the method of judging collection, natural or social phenomena from the results obtained from the analysis or enumeration or collection of estimates”*

*“statistics are the numerical statement of facts capable of analysis and interpretation and the science of statistics is the study of the principles and the methods applied in collecting, presenting, analysis and interpreting the numerical data in any field of inquiry.”*
