2. OBJECTIVES
At the end of the lesson, the students should be able to:
• synthesize the knowledge about the appropriate use of
graphs to represent organized data;
• illustrate line plot and stem – leaf plot in organizing data;
and
• show evidence of mastery through drills and group
exercises.
3. Let’s see HOW you DID it…
Construct a pie graph given the tabular data on the
population of students enrolled in USTJHS for the
A.Y. 2015 - 2016

Let’s see HOW you DID it…
5. Use a bar graph if you are not looking for trends
(or patterns) over time; and the items (or
categories) are not parts of a whole.
Use a line graph if you need to see how a
quantity has changed over time. Line graphs
enable us to find trends (or patterns) over time.
Use a pie chart if you need to compare different
parts of a whole, there is no time involved and
there are not too many items (or categories).
CHOOSING THE RIGHT GRAPH
Learning Objective: Students should be able to synthesize the knowledge about the
appropriate use of graphs to represent organized data.
6. CONCEPTUAL CHECK
Which statistical graph best fit for the set of data?
The allocation of the monthly budget of a
family
Learning Objective: Students should be able to synthesize the knowledge about the
appropriate use of graphs to represent organized data.
CIRCLE GRAPH
7. CONCEPTUAL CHECK
Which statistical graph best fit for the set of data?
The donations by each grade level of UST
High School for the victims of Typhoon
Yolanda
Learning Objective: Students should be able to synthesize the knowledge about the
appropriate use of graphs to represent organized data.
BAR GRAPH
8. CONCEPTUAL CHECK
Which statistical graph best fit for the set of data?
Changes in temperature over a week in
Manila
Learning Objective: Students should be able to synthesize the knowledge about the
appropriate use of graphs to represent organized data.
LINE GRAPH
9. CONCEPTUAL CHECK
Which statistical graph best fit for the set of data?
The number of members per grade level
for the Math Club for
S.Y. 2014 – 2015
Learning Objective: Students should be able to synthesize the knowledge about the
appropriate use of graphs to represent organized data.

16. ENGAGE YOURSELF!
The following data shows the highest score of 16
students from St. Bernadette in the Flappy Bird
game:
107 105 115 108 106 106 109 110
110 108 114 115 115 113 115 108
How are you going to
organize this data in
order to make it
presentable?
17. LINE PLOT
Steps:
1. Determine the highest and the lowest values in
the data.
2. Construct a number line.
3. Put an “x” above each number as many times it
appears in the data.
