Define Data Presentation
Data presentation is defined as the process of using various graphical
formats to visually represent the relationship between two or more data
sets so that an informed decision can be made based on them.
Types of Data Presentation
Broadly speaking, there are three methods of data presentation:
Textual
Tabular
Diagrammatic
Textual Ways of Presenting Data
Out of the different methods of data presentation, this is the most simple
one. You just write your findings in a coherent manner and your job is
done. The demerit of this method is that one has to read the whole text to
get a clear picture. Yes, introduction, summary and conclusion can help
condense the information.
Tabular Ways of Data Presentation and Analysis
To avoid the complexities involved in the textual way of data presentation,
people use tables and charts to present data. In this method, data is
presented in rows and columns - just like you see in a cricket match
showing who made how many runs. Each row and column has an
attribute (name, year, sex, age and other things like these). It is against
these attributes that data is written within a cell.

Statistics
This kind of data presentation and analysis method says a lot with
dramatically short amounts of time.
Diagrammatic Presentation has been divided into further categories:
,Geometric Diagram
When a Diagrammatic presentation involves shapes like a bar or circle, we
call that a Geometric Diagram. Examples of Geometric Diagram
Bar Diagram
Simple Bar Diagram
Simple Bar Diagram is composed of rectangular bars. All of these bars
have the same width and they are placed at an equal distance from each
other. The bars are placed on the X-axis. The height or length of the bars is
used as the means of measurement. So on the Y-axis, you have the
measurement relevant to the data.
Suppose, you want to present the run scored by each batsman in a game
in the form of a bar chart. Mark the runs on the Y-axis - in ascending order
from the bottom. So the lowest scorer will be represented in the form of
the smallest bar and highest scorer in the form of the longest bar.

Multiple Bar Diagram
In many states of India, electric bills have bar diagrams showing the
consumption in the last 5 months. Along with these bars, they also have
bars that show the consumption happened in the same months of the
previous year. This kind of Bar Diagram is called Multiple Bar Diagrams.

, Component Bar Diagram
Sometimes, a bar is divided into two or more parts. For example, if there is
a Bar Diagram, the bars of which show the percentage of male voters who
voted and who didn’t and the female voters who voted and who didn’t.
Instead of creating separate bars for who did and who did not, you can
divide one bar into who did and who did not.
Pie Chart
A pie chart is a chart where you divide a pie (a circle) into different parts
based on the data. Each of the data is first transformed into percentage
and then that percentage figure is multiplied by 3.6 degrees. The result
that you get is the angular degree of that corresponding data to be drawn
in the pie chart. So, for example, you get 30 degrees as the result, on the
pie chart you draw that angle from the centre.

Frequency Diagram
Suppose you want to present data that shows how many students have 1
to 2 pens, how many have 3 to 5 pens, how many have 6 to 10 pens
(grouped frequency) you do that with the help of a Frequency Diagram. A
Frequency Diagram can be of many kinds:
Histogram
Where the grouped frequency of pens (from the above example) is written
on the X-axis and the numbers of students are marked on the Y-axis. The
data is presented in the form of bars.
