1. MEASURE OF CENTRAL
TENDENCY
OF UNGROUP DATA

2. define mean, median and mode;
show appreciation to the value of mean, median and mode in
real life situation.
Illustrates the mean, median, and mode for ungrouped data.

At the end of 60-minute period, the students should be
able to:

3. Is a data given as
individual data
points.
UNGROUPED DATA

4. The following are
the math’s scores
of a class:
How can the teacher
summarize this
data?
18, 15, 19, 16, 20,
14, 17, 12, 20, 13,
18, 19, 16, 20, 11

5. Arrange Yourselves!
Arrange yourselves according to your birth month:
Question:
a. What birth month appear the most frequent among the
group of students?
b. If we are going to get the average data of your birth
month by adding all your ages divided by the number of
students, what will be its average?
c. What is the middle value of the data from least to
greatest?

6. Mean
Median
Mode
Measure of Central Tendency of
Ungrouped Data

7. For Example
BOYS HEIGHT IN CM
Let’s find the mean of the math’s scores:

8. Formula for finding the
Mean

9. To find the Mean:
Let’s find the mean of
the math’s scores:
Mean
16.5
18 + 15 + 19 + 16 + 20 +
14 + 17 + 12 + 20 + 13 +
18 + 19 + 16 + 20 + 11

10. Median
is the middlemost
value of the data
set.

11. Median
is the middlemost
value of the data
set.

12. To find the Mode:

Tomorrow, we will apply these concepts
to more complex problems.
