The document discusses various types of graphs for data presentation, emphasizing the importance of selecting the appropriate graph for different data sets. It covers line graphs, bar graphs, histograms, and pie charts, explaining their uses and how to interpret them effectively. Each graph type is illustrated with examples to demonstrate their application in conveying information effectively.

1. Kinds of Graphs for
Data Presentation

2. • A graph is an alternative way to present data.
It involves a lot of communication power.
• A quick look of these graphs may enable the
reader to have an instant and meaningful
picture of the vast amount of data.

3. Different data call for different graphs. The
graphs may all look brilliant, but is it the
right graph for the data? In this lesson, we
will learn how to compare and contrast
different graphs and determine which type
of graph is appropriate for representing a
given set of data presented.

4. Definition of Graph
• It is an alternative way to present data.
• It involves a lot of communication power.
• In businesses, it is used to help them
convey information and to make sense of
data.
• It always describes something about
business

5. • Line graph - uses line segments to connect
data points. It is useful in showing the trends
or in determining relationships between two
variables. It can also be applied if the
variable plotted along the X-axis (horizontal
line) is related to time (year, month, day,
clock time)
Most commonly used different kinds of graphs

6. Different Kinds of Graphs
• a. Line Graph
Example
• a. Title: The title is the heading written on top of the graph.
• b. Scale: Do not forget the numbers on the X-axis which indicates the units of time.
On the Y-axis, the numbers indicate the units of frequency. Be cautious on the scale of
the Y-axis. If the scale is set too high or too low, the trends in the data can be misleading.

7. DifferentKindsofGraphs
• a. Line Graph
Example
• c. Labels: Identify the variables on the X- and Y-axes.
• d. Data points: Plot all the data points on the X- and Y-axes. Each
data point is connected to the next point by a line.

8. Different Kinds of Graphs
• a. Line Graph
Example #1
• e. Line: Create the line by connecting all data points.
• f. Description: It will be helpful if you will have an explanation of
your graph.
In example 1, the line escalates every week. But a tremendous increase
was shown from Week 5 to Week 6.

9. Different Kinds of Graphs
• a. Line Graph
o Example #2
The sales trend of product X in Store A and Store B can be seen in one
graph. It is easier to compare trends when they are represented on the
same graph. The sales of product X in Store A is consistently higher
than the sales of product in Store B.

10. • Bar graph - uses rectangles erected on
the horizontal axis to summarize a set of
quantitative data. Here, the height of the
bar represents the measured value or
frequency; that is. The higher or taller the
bar, the greater the value.
Most commonly used different kinds of graphs

11. b. Bar Graph
Example
Aura Pension House offers three types of rooms, Traveler,
Executive, and Superior. The sales of each type are plotted on
the vertical axis, and the types of room are on the horizontal
axis.
It is easy to compare the trends of each type over a three-year
period. Superior is the highest selling among three, but has
dropped off over the three-year period, while sales of the other
two have continued to grow.
Which graphical presentation can approximately model this
observation?

12. b. Bar Graph
Example

13. b. Bar Graph
Example
When you need more spaces to describe the measured
variable, it is advised to represent the data by horizontal
bar graphs. The variables can be written on the vertical
axis and the horizontal axis assumes the continuous data.

14. b. Bar Graph
Example
Different Kindsof Graphs
The high school students were asked on their preferred dishes. The
number of dishes is plotted on the vertical axis while the type of dish
is plotted on the horizontal axis. Most students prefer chicken
barbecue while on the other hand, fish fillet is the least preferred
dish.

15. • Histogram - is a graphical representation
of the frequency distribution. It is a
representation of tabulated frequencies (Y-
axis) using adjacent erected rectangles
with their corresponding class intervals
(X-axis)
Most commonly used different kinds of graphs

16. Example

17. • Pie graph - is also called a circle graph. It is
circle with the wedges or sectors to show
how much of the whole each part makes up.
Each slice of the pie is written as a
percentage. To get the measure of each sector in
the chart, we compute the following:
amount of item over the total amount of all items
multiplied by 360°.

18. Different Kinds of Graphs
d. Pie graph is also called a circle graph. It is a circle
with the wedges or sectors to
show how much of the whole each part makes up.
Each slice of the pie is written as
percentage.
