                                                Importance of graphic presentation 

The main advantages or graphic presentation of data are as follows:  

  1.    Graphic presentation is a very effective technique of data presentation.

  2.     Using graphic technique, we can easily locate the value of certain averages.

  3.    Graphic presentation facilities interpolation and extrapolation of the data in a more convenient and precise manner.

  4.    Graphic technique help in studying correlation between different variables.

  5.    Data of different dimensions can be easily compared with the help of graphic presentation.

  6.    Graphic technique help us in entertainment as well as for providing information.

  7.    Graphic technique help in the process of transmission as well as information of facts.

Types of variable

     

               Types of variable

  1.   Qualitative variable: The variables which assume non numerical values are called qualitative variable. For example religion, education, profession,etc.

  2.   Quantitative variable: The characteristics of an unit or item that are expressed in numerical form or in numbers are called quantitative variable. For example, weight, length, size, age, production etc.

Quantitative variable can further be classified into two sub groups

(a). Discrete variable: The variables which values can be expressed through a separate number are called discrete variable. For example number of children of a family, obtained marks in examination etc.

(b) continuous variable: The variables which values can not be expressed through a specific number are called continuous variable. For example, Height, Weight, etc. -7

Limitation of statistics

                                                         Economic of statistics

          Limitation of statistics

The scope of statistics is very wide and it has great utility. But statistics has limitations, some of which are discussed below:

1.  Statistics can analysis an aggregated observation or data: any statistics is a collection of data. Individual observation does not belong to statistics. Hence statistics analysis a collection of data and enlighten the overall estimated result.

2.  Statistics describes by numerical information: Statistics is an exposure of the numerical data. If it is not possible to express in a figure. Statistics fail to make a comparative study between rich and poor, sound and ill etc. abstact topics.

3.  Statistics given only an overall measures: Statistics give us only an average or overall estimation. It is almost impossible.

It is also possible to predict the course of events in the future on the basis of past experience with the help of statistical data. Briefly, the functions of statistics are:

1.    To present facts in a definite form : The main function of statistics is to present general statement in definite and specific form. It also presents data and information in a precise and definite form and therefore comparisons.

2.  To simplify complex data so as to make them understandable: statistics present facts indefinite form and helps in condensing a huge data into a significant figure. It also helps in simplifying the complex data so as to make them understandable.
