Statistics From Wikipedia, the free encyclopedia Jump to: navigation, search This article is
about the discipline. For other uses, see Statistics (disambiguation). Statistics is the study of the
collection, organization, analysis, interpretation and presentation of data.[1][2] It deals with all
aspects of this, including the planning of data collection in terms of the design of surveys and
experiments.[1] A statistician is someone who is particularly well-versed in the ways of thinking
necessary for the successful application of statistical analysis. Such people have often gained
experience through working in any of a wide number of fields. There is also a discipline called
mathematical statistics that studies statistics mathematically. The word statistics, when referring
to the scientific discipline, is singular, as in \"Statistics is an art.\"[3] This should not be confused
with the word statistic, referring to a quantity (such as mean or median) calculated from a set of
data,[4] whose plural is statistics (\"this statistic seems wrong\" or \"these statistics are
misleading\"). More probability density will be found the closer one gets to the expected (mean)
value in a normal distribution. Statistics used in standardized testing assessment are shown. The
scales include standard deviations, cumulative percentages, percentile equivalents, Z-scores, T-
scores, standard nines, and percentages in standard nines. Contents 1 Scope 2 History 3

Scope Some consider statistics to be a mathematical body of science pertaining to the collection,
analysis, interpretation or explanation, and presentation of data,[5] while others consider it a
branch of mathematics[6] concerned with collecting and interpreting data. Because of its
empirical roots and its focus on applications, statistics is usually considered to be a distinct
mathematical science rather than a branch of mathematics.[7][8] Much of statistics is non-
mathematical: ensuring that data collection is undertaken in a way that allows valid conclusions
to be drawn; coding and archiving of data so that information is retained and made useful for
international comparisons of official statistics; reporting of results and summarised data (tables
and graphs) in ways that are comprehensible to those who need to make use of them;
implementing procedures that ensure the privacy of census information. Statisticians improve
the quality of data by coming up with a specific design of experiments and survey sampling.
Statistics itself also provides tools for prediction and forecasting the use of data and statistical
models. Statistics is applicable to a wide variety of academic disciplines, including natural and
social sciences, government.

For the last few centuries, statistics has remained a part of mathematics as the original
work was done by mathematicians like Pascal (1623-1662), James Bernoulli (1654-1705),
De Moivre (1667-1754), Laplace (1749-1827), Gauss (1777-1855), Lagrange, Bayes,
Markoff, Euler etc. These mathematicians were mainly interested in the development of
the theory of probability as applied to the theory of games and other chance phenomena.
Till early nineteenth century, statistics was mainly concerned with official statistics needed
for the collection of information on revenue, population and area of land under cultivation
etc. of a state or kingdom.
The science of statistics developed gradually and its field of application widened day
by day. Hence, it is difficult to give an exact definition of statistics. The definition changed
from time to time depending upon its use and application. Numerous definitions have
been coined by different people. These definitions reflect the statistical angle and field of
activity.
Statistics as a subject (field of study):
Statistics is defined as the science of collecting, organizing, presenting, analyzing and interpreting numerical data to make decision on the bases of such analysis.(Singular sense)
Statistics as a numerical data:
Statistics is defined as aggregates of numerical expressed facts (figures) collected in a systematic manner for a predetermined purpose. (Plural sense) In this course, we shall be mainly concerned with statistics as a subject, that is, as a field of study

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

2. INTRODUCTION
In the modern world of computers and information
technology, the importance of statistics is very well
recognized by all the disciplines. Statistics has
originated as a science of statehood and found
applications slowly and steadily in Agriculture,
Economics, Commerce, Biology, Medicine, Industry,
planning, education and so on. As on date there is no
other human walk of life, where statistics cannot be
applied.
3. ORIGIN AND GROWTH OF STATISTICS
The word ‘ Statistics’ and ‘ Statistical’ are all derived
from the Latin word Status, means a political state.
The theory of statistics as a distinct branch of
scientific method is of comparatively recent growth.
Research particularly into the mathematical theory of
statistics is rapidly proceeding and fresh discoveries
are being made all over the world.
4. MEANING OF STATISTICS
Statistics is concerned with scientific methods for
collecting, organizing, summarizing, presenting and
analyzing data as well as deriving valid conclusions
and making reasonable decisions on the basis of this
analysis. Statistics is concerned with the systematic
collection of numerical data and its interpretation. The
word ‘ statistic’ is used to refer to
1. Numerical facts, such as the number of people
living in particular area.
2. The study of ways of collecting, analyzing and
interpreting the facts.
5. DEFINITIONS
Statistics is defined differently by different authors
over a period of time. In the olden days statistics was
confined to only state affairs but in modern days it
embraces almost every sphere of human activity.
Therefore a number of old definitions, which was
confined to narrow field of enquiry were replaced by
more definitions, which are much more
comprehensive and exhaustive. Secondly, statistics
has been defined in two different ways Statistical data
and statistical methods. The following are some of the
definitions of statistics as numerical data.
6. CONT..
1. Statistics are the classified facts representing
the conditions of people in a state. In
particular they are the facts, which can
be stated in numbers or in tables of
numbers or in any tabular or classified
arrangement.
2. Statistics are measurements, enumerations or
estimates of natural phenomenon usually
systematically arranged, analyzed and
presented as to exhibit important
interrelationships among them.
7. DEFINITIONS BY A.L. BOWLEY
Statistics are numerical statement of facts in any
department of enquiry placed in relation to each
other. - A.L. Bowley Statistics may be called the
science of counting in one of the departments due to
Bowley, obviously this is an incomplete definition as it
takes into account only the aspect of collection and
ignores other aspects such as analysis, presentation
and interpretation.
8. CONT.…
Bowley gives another definition for statistics, which
states‘ statistics may be rightly called the scheme of
averages’ . This definition is also incomplete, as
averages play an important role in understanding and
comparing data and statistics provide more
measures.
9. DEFINITION BY CROXTON AND COWDEN
Statistics may be defined as the science of collection,
presentation analysis and interpretation of numerical
data from the logical analysis. It is clear that the
definition of statistics by Croxton and Cowden is the
most scientific and realistic one. According to this
definition there are four stages:
10. COLLECTION OF DATA
It is the first step and this is the foundation upon
which the entire data set. Careful planning is
essential before collecting the data. There are
different methods of collection of data such as
census, sampling, primary, secondary, etc., and the
investigator should make use of correct method.
11. PRESENTATION OF DATA
The mass data collected should be presented in a
suitable, concise form for further analysis. The
collected data may be presented in the form of
tabular or diagrammatic or graphic form.
12. ANALYSIS OF DATA:
The data presented should be carefully analyzed for
making inference from the presented data such as
measures of central tendencies, dispersion,
correlation, regression etc.,
13. INTERPRETATION OF DATA
The final step is drawing conclusion from the data
collected. A valid conclusion must be drawn on the
basis of analysis. A high degree of skill and
experience is necessary for the interpretation.
