The document discusses different types of data graphs used to present numerical data. It describes 6 common graphs: pictograph, bar graph, double bar graph, pie chart, histogram, and line graph. For each graph type, it provides an example of what each graph looks like and how it represents data. It explains that data handling involves collecting raw data and presenting it in different visual forms to more easily understand and analyze information.

Introduction
Topic = Data Handling

2. Data handling means collecting the
set of data and presenting in a
different form. Data is a collection of
numerical figures that represents a
particular kind of information. The
collection of observations which are
gathered initially is called the raw
data. Data can be in any form. It
may be words, numbers,
measurements, descriptions or
observations.
What is a Data handing?

3. I mention 6 Data graphs in this
presentation :-
1. Pictograph
2. Bargraph
3. Double Bar Graph
4. Pie Chart
5. Histogram
6. Line Garph
Types of Data :-

4. The representation of the
information through pictures is
called pictograph. A certain
number of items is
represented by each picture.
Example:-The pictograph
shows the profits earned by a
company each year from 2018
to 2021
Pictograph

5. A bar graph is the
representation of numerical
data by Bar of equal width and
varying height. The gap
between one bar and another
is uniform throughout.
Example:- : Graph to represent
season’s liked by students of a
class
Bargraph :-

6. Double Bargraph :-
A double bar graph is the
graphical representation of
grouped data. In a double bar
graph, two bars are drawn for
each category. These two bars
represent the two given
parameters for each category.
example:- Marks of students
Gained in Maths & Enaglish

7. Piechart:-
The pie chart is also known as
a circle graph. It shows how a
whole is divided into different
parts. The pie chart shows the
relative size of each data set in
proportion to the entire data
set.
Example :- Games loved by
students in a class.
15%
24%
19%
32%
10%
Games liked by students
Cricket
Football
Kho-kho
Kabaddi
Badminton

8. A histogram is a graphical
representation of data points
organized into user-specified
ranges. Similar in appearance
to a bar graph, the histogram
condenses a data series into
an easily interpreted visual by
taking many data points and
grouping them into logical
ranges or bins.
Histogram:-

9. Linegraph:-
A line graph, also known as a
line chart or a line plot, is
commonly drawn to show
information that changes over
time.
Example:- Simple line graphs:
It is formed when you draw
just one line to connect the
data points. It is also known
as a linear graph. This Graph
shows the Earnings of the
