The discipline is useful in converting random data to understandable information
and aids in strategic business decision making.
Statistics has its origin in Latin word Status, Italian word Statista and German term
Statistik all of which mean "Political State".
In ancient times the beginning of Statistics was made to meet the requirements of
State primarily and hence the name.

•

Statistics may be defined as the collection, presentation, analysis and interpretation of numerical data. Statistics is a set of decision-making techniques which helps businessmen in. 

Scene 4

Statistics may be defined as the collection, presentation, analysis and
interpretation of numerical data.
Statistics is a set of decision-making techniques which helps businessmen in

making suitable policies from the available data. In fact, every businessman needs
a sound background of statistics as well as of mathematics.
The purpose of statistics and mathematics is to manipulate, summarize and
investigate data so that the useful decision-making results can be executed.

• Two branches of statistics 1) Descriptive statistics 2) inferential statistics 1) Descriptive statistics: descriptive statistics state facts and proven outcomes from a. 

Scene 5

• Two branches of statistics
1) Descriptive statistics
2) inferential statistics
1) Descriptive statistics: descriptive statistics state facts and proven outcomes from a

Descriptive statistics summarize and describe data
2) inferential statistics : inferential statistics analyze samplings to make predictions
about larger populations.
Inferential statistics draw conclusions and make predictions about populations based
on sample data.

• The scores of 2 groups of students belonging to different classes are noted.

With the help of statistical methods, quantitative information about production, sale, purchase, finance, etc. can be obtained. This type of information helps businessmen in formulating suitable policies.. 

Scene 6

With the help of statistical methods, quantitative information about
production, sale, purchase, finance, etc. can be obtained.
This type of information helps businessmen in formulating suitable
policies.

• By using the
ques ot
e series analysis which are based on
statistical methods, the businessman can predict the effect of a large
number of variables with a fair degree of accuracy.
In business decision theory, most of the statistics techniques are used in
taking a business decision which helps us in doing the business without
uncertainty.

BASIC DEFINITION OF STATISTICS. • "Statistics may be called as science of counting." • "Statistics may rightly be called the science of averages.". 

Scene 8

• -Bowled
'By statistics we mean qualitative data affected to a marked extent by a multiplicity
of causes." - Yule and Kendall.

law of consumption, Pareto's law of distribution of income etc.

Statistics are used in various filed:
Examples:
1) Statistics and Economics

• Statistical tools and techniques of data analysis such as price index numbers, time series 
analysis, demand analysis etc. Have proved immensely useful in solving a variety of economic 
problems.
