1. Textual Presentation

In Textual presentation, data are a part of the text of studyor a part of the description of the subject matter of study.Such a presentation is called descriptive presentation ofdata.

This data is the most common form of data presentationwhen the quantity of data is not very large.

Textual presentation of data is most suitable when thequantum data is not very large.

Example: In 2008 – 09, total production of foods grains was 2,344 lakhtonnes of which production of rice, wheat and other crops was 992,807 and 545 lakh tonnes, respectively. Percentage share of rice, wheatand other crops in the total production of food grains was 42.32, 34.43and 23.25 respectively.

2. Tabular Presentation

In the words of Neiswanger, “A statistical table is asystematic organization of data in columns and rows.

Components of a Table:-

• Table Numbers

• Title

• Head Note

• Stubs

• Caption

• Body or Field

• Footnotes

• Source

Let us be Practical: Table 1: Production of Food Grains in India

in 2008-09(Total in Lakh Tonnes, and Percentage)

Footnote: In ‘others’, all remaining food grains are included

Source: Economic Survey, 2010-11

Let us construct a table,showing its variouscomponents, given thefollowing information:In 2008 – 09, total productionof foods grains was 2,344lakh tonnes of whichproduction of rice, wheat andother crops was 992, 807 and545 lakh tonnes, respectively.Percentage share of rice,wheat and other crops in thetotal production of foodgrains was 42.32, 34.43 and23.25 respectively.

Guidelines for the construction of a Table or Features of a Good table (see text book page 89 & 90)

Kinds of TableThere are three basis of classifying tables:-

1. Purpose of a table

2. Originality of a table

3. Construction of a table

1. According to Purpose of a table:-

a) General Purpose Table: It is that table which is of general use. It does not serve any specific purpose.

b) Special Purpose Table: It is that table which is prepared with some specific purpose in mind.

2. According to Originality of a table:-

a) Original Table: It is that table in which data are presented in the same form andmanner in which they are collected.

b) Derived Table: It is that table in which data are not presented in the same formand manner in which these are collected. Instead the data are first converted intoratios or percentage and then presented.

3. According to Construction of a table

1. Simple or One way Table: It shows only one characteristic of the data. It shows numberof students in a college:

2. Complex Table : It shows more than one characteristic of the data.

(a) Double or Two-way Table: Table According to Class and Sex.
