What is Nature of Statistics
Statistics is a
scientific method of doing things; it should not be thought of a subject
correlative with physics, chemistry, economics and sociology, it is not a
science but it is purely a scientific method. In order to understand the nature
of statistics, we must look at it as we see that statistics is not mathematics
just as Accounting is not mathematics, although the statistical methods are
basically mathematical.
In the modern
world phenomena are many and various, such as Chemical, Physical, Biological,
Geographical, Social, Psychological, Economic, Business, etc. Each of these
phenomena has its own peculiarities, characteristics and problems. For studying
any phenomena for some practical purposes, some method is required. There are
various statistical methods that can be used in studying certain phenomena in
order to enable the people to understand how the problems raised and how it can
be prevented if the need arises.
The nature of the statistics is understood
from what kind of scientific method that is. It is a scientific method by which
the statistician collects facts, classify facts by their mutual relation and
describe their sequences or draw an inference. The techniques of statistics, as
a part of the general scientific method, may be summed up in three words,
namely, Description, Comparison and Interpretation. It is by the application of
techniques that the problems are studied such problems may relate to any
phenomena such as Physical, Chemical, Biological, Social, Economic, Psychological,
and Business etc. Therefore, the nature of statistics is not a science as a
subject, but it is a method of application, which is called the scientific
method of reasoning with facts to find ways to made decision which will help in
solving problems.
The nature of
statistics explains that the statistician using the methods are concerned with
presentation and interpretation of chance outcomes that occurs in a planned
study or a scientific investigation. And we may also look at its nature from the
way it works, statistical methods are those procedures used in the collection,
presentation, analysis and interpretation of data. These methods belong to
descriptive statistics. Descriptive statistics comprises those statistical
methods concerned with collecting and describing a set of data so as to yield meaningful
information, such work involves things like construction of tables, charts,
graphs and other relevant computations from the data taken from the various
newspapers and from research organizations.
The ultimate objectives in
statistical studies is to make decisions and conclusions about a large set of
data. Therefore, statistical inference comprises those methods concerned with
the analysis of a subset of data leading to predictions or inferences about the
entire set of data.
