The document is a lesson plan focusing on deciles, intended to educate students on how to calculate and illustrate measures of position within data sets. It includes examples, activities for group participation, and assessment tasks related to understanding deciles. Additionally, students are assigned to watch a video on percentiles for future discussions.

11. Learning
Outcomes
By the end of the lesson, you'll
be able to learn how to:
illustrate the measures of position
using decile.
calculate a specified measure of
position of a set of data using decile.
solve problems involving measures of
position using decile.
display cooperation with a group in
doing the activity.

13. What do you know about deciles?
DECILE
- Decile are nine score-points that divide a
distribution into ten equal parts. The word
Decile was first known used on 1882, it comes from
the Latin word decem ten – it means more at Ten.
The formula used in solving for the Decile is

14. What can you see?
DECILES
There is 9 distribution in 10 parts
D1 D2 D3 D4 D5 D6 D7 D8 D9

15. Let’s Try solving for
Deciles

16. Example 1 2nd Decile
13, 5, 17, 4, 6, 12,
19, 10 8
Arrange in ascending order:
4, 5, 6, 8, 10, 12, 13, 17,19
Use the formula:
erefore, 20% of the students
red 5 or below
The list below shows the test
scores of Grade 10 students in
their Mathematics quiz.
Calculate the 2nd
Decile.

17. You are tasked by your Physical
Education teacher to get the
weight of your group mates to
solve for your BMI as he would
like to know the average weight
of your team. The average is
located at the 5th decile.
Example 2 5th Decile
46, 43, 47, 50, 49,
48, 54, 56, 52
Arrange in ascending order:
43, 44, 46, 47, 48, 49, 50, 52,
54
Use the formula:
Therefore, 50% of the students
weigh 48 kilograms or below.

the data?
“RECAP”
* What is a decile?
* What is the formula for decile?

22. “RECAP”
* As a student, why do you think
it is important that you know how
to be organized and set things in
order?

23. “RECAP”
* Why do you think it is
important to use decile in some
situations?

24. ASSESSMENT
Solve for the 3rd and 5th decile:
12, 14, 17, 19, 11, 9, 6, 16, 10
In your 1/2 sheet of pad paper. Answer
this individually. You have 5 minutes to
answer your assessment.

25. Assignment
1 Janine lists down their electric bill for the year 2023. Solve
and look for the 5th decile.
Here are the bills from January to December respectively:
980, 965, 1120, 1450, 1800, 1100, 975, 785, 680, 780, 920,
