Tabular Presentation of Data Class 11 Notes

This chapter is all about tables. We have to learn the parts, merits, and kinds of tables. Here are the tabular presentation of data class 11 notes.

Tabular Presentation

Data are a part of the text of the study or a part of the description of the subject matter of study.

A small volume of data presented as a part of the subject matter of study became useful supportive evidence to the text.

It involves the orderly & systematic presentation of numerical data in a form designed to elucidate the problem under consideration.

Although there are many parts of a table but main parts of a table are these:

Table Number: This is a unique number given to a table for ease of finding it. This is usually like 5.1 showing the number one table in chapter 5 of any book.
Title: It shows what the table is all about. For example: If the table title is Heights of Students then it shows the table is all about the height of students.
Stubs: This is used to tell what all the rows are about. For example: If three rows are showing Science, Commerce, and Arts then Stub would be showing Streams.
Caption: This is almost the same as stubs but it shows the columns heading.
Body or Field: This is where the main content comes from. A major detail of a table is shown in this part.
Head Note: It is to be read before the table but after the title.
Source Note: It shows where the information in the table has been taken from.
Foot Note: These show the additional information apart from the table but related to the topic.

Features of a good table are as follows:

Diagrammatic data is a simple & attractive manner in the form of diagrams. Diagrammatic presentation is broadly classified into three types i.e.

Bar diagrams are those diagrams in which data are presented in the form of bars or rectangles.

Simple bar diagrams are based on a single set of numerical data. The different items or values are represented by different bars.

Data related to birth rate, death rate, production level, etc. are generally presented as a simple bar graph.

Diagrams that show two or more sets of data simultaneously are called multiple bar diagrams.

Generally, these diagrams are used to compare two sets of series, such as the birth rate or death rate series.

Separate bars are drawn to present separate sets of values.

Diagrams that simultaneously present, total values as well as part values of a set of data are known as sub-divided bar diagrams.

Different parts of the bars are shaded with colors. Different parts of the bars must be shown in the same order for all diagram bars.

The percentage bar diagram shows simultaneously different parts of the values of a set of data in terms of percentages.

The percentage bar diagram is used generally when the values are of high magnitude.

Note: The total value, indicated by the total length of a bar is assumed to be 100. Each part there is shown as a part of 100.
