This document discusses different methods for presenting data, including textual, tabular, and graphical presentation. Tabular presentation organizes data into rows and columns in a table. Textual presentation uses statements and numbers to describe data. Graphical presentation shows variations and relationships of data using visual formats like bar graphs, line graphs, and pie charts. Each method has advantages - tables provide concise information while graphs attract attention and enable quick comprehension of quantitative data relationships.
2. What is presentation?
It is the process of organizing data into logical
and meaningful categories and classification to
make them amenable to study.
3. What is data?
A collection of facts and figures that needs to be
justified.
4. PRESENTATION OF DATA
The presentation of data means exhibition of the data in
such a clear and attractive manner that these are easily
understood and analyzed. There are many forms of
presentation of data.
6. Tabular Presentation
in the process of Tabular presentation, data is
organized in rows and columns.
the method used is known as Tabulation
( presenting data in the form of rows and columns
in a table ).
7. Textual Presentation of Data
-uses statements with numerals or numbers to
describe data.
-the main aims of textual presentation is to focus
attention to some important data and to
supplement tabular presentation
8. Graphical Presentation of Data
-a graph is a chart representing the quantitative variations or
changes of a variable itself or quantitative changes of a variable in
comparison with those of another variable changes in data may
refer to their qualitative, geographical or chronological attributes
-its purpose is to present the variations, changes and relationship
of data in a most attractive, effective and convincing way
9. Advantages of Tabular over Textual
Statistical tables are concise
Data are more easy to read: and
Tables give the whole information even without
combining numerals with textual matter
10. Advantages of Graphical Method
Attracts attention more effectively than to tables.
Use colors and pictorial diagrams.
Gives comprehensive view of quantitative data.
Enable to grasp the essential facts quickly without much
trouble.
11. Disadvantages of Graphs
Do not show information at a time as tables do.
Do not show data as accurately as the tables do.
Require more skill, more time, and more expense to
prepare than tables.
Can be made only after the data have been tabulated.
12. Types of Graphs or Charts
Bar Graph- use to make comparison of simple magnitudes more
clearly and distinctly.
Linear Graph- are good to show variations of values over
successive periods of time.
Pie Chart (Circle Graph)- a circular chat that illustrates relative
magnitudes frequencies.
