IV. PROCEDURES
Before the Lesson
Preparatory Activity
 Prayer
Teacher’s Activity
Before starting our day, let’s all stand and pray first.
(The student will lead the prayer)
 Greetings
Good morning, Class!
 Checking of
Attendance
Let me check your attendance first. Who is absent?
A. Reviewing previous
lesson or presenting the
new lesson
Let the students recall on what they understand about Statistics.
Just a simple recap, Statistics is a branch of mathematics that deals with the study of
defining a problem, collecting, organizing, analyzing and interpreting data for the
purpose of drawing conclusions.
If we were to understand the definition of Statistics, statistics is the guide on how to
solve a problem considering that we need to follow a procedure.
During the Lesson
B. Establishing purpose for
the lesson
Today’s discussion is about Statistical Instrument. What does it mean when we say
Statistical Instrument?
A Statistical Instrument is any process that aim at describing a phenomena by
using any instrument or device.
C. Presenting Examples
In statistics, it is us who will find a problem and at the same time find also an
answer on our chosen problem. For us to answer, we should develop a
statistical instrument that will be used to gather data. Some of these statistical
instruments are questionnaires and rating scales.
A questionnaire is a printed list of questions to be answered by respondents to
collect data.
2 Types of Questionnaire:
1. Structured or Closed Format – the questions in this format consist of questions
that have one answer only. There may be a few questions that require more than one
answer. Some of the examples of this format are multiple choice and alternative
response questions such as true-or-false.
Examples:
o
Are you in favor of an additional two years in the high school
curriculum?
____ YES
o
___ NO
Which of the following fast-food chains do you like the most?
____ Jollibee
____ KFC
____McDonald’s
____ Greenwich
2. Unstructured or Open Format – the questions in this format can have different
answers. There are no limits as to the responses of respondents.
Examples:
-
What do you think are the reasons of cyber bullying?
-
Why did you choose to study here at Palompon National High School?
Rating Scales are often used in survey research to ask the respondents to rate or
select a response in ranked manner. One common example is the Likert Scale.
Example:
The economic status of the country is improving.
1 – Strongly Agree
2 – Disagree
3 - Neutral
4 – Agree
5 – Strongly Agree
D. Discussing New
Concepts & Practicing
Skills
-
Among the 2 statistical instruments, which is the easiest way to
construct or to make?
For you to be familiar with the 2 types of questionnaire. Let us determine the type
of question given, Structure Format or Unstructured Format.
1. What brand of coffee do you prefer?
2. Are you in favor of the K-12 Program?
3. Why is Mathematics your favorite subject?
4. Is it true that a starfish is a fish?
Can you now differentiate the difference between the 2 formats of questionnaire?
Next is for the Rating Scale type of Statistical Instrument, we will be making a
question and the answer is in rating scale.
For example:
Using the rating scale
1 – Strongly Agree
2 – Disagree
3 - Neutral
4 – Agree
5 – Strongly Agree
Let us answer this question:
-
Education will help me to get a good job in the future.
-
My parents attend meeting when they are called by the school.
-
Our teacher encourages us to work hard.
-
My parents encourage me to work hard in my studies.
-
Our teacher always make sure that we understand the lesson.
After the lesson
E. Developing Mastery
We will be having an activity; you choose a partner and then you will be asking
your partner 3 structured and unstructured format of question. 5 minutes to do this
and pass your paper after.
Next activity is, you group yourself into four and then make 5 questions that is
answerable by this rating scale:
1 – Strongly Agree
2 – Disagree
3 - Neutral
3 – Agree
4 – Strongly Agree
F. Finding practical
Application
Let me ask you class, if you are trying to find an answer to a question what will you
do?
This statistical instrument is not only applicable for math, this will also help us in
our daily lives on how are we going to make a question for us to have an answer to
our “what if’s” and queries. At the same time, we are knowledgeable enough if we
will be investigating something that we are really and really curious about, to our
friends’ story, our family experiences, if your mom and dad fought and all of your
questions that needs an answer.
G. Making generalizations
What is a statistical instrument?
What are the 2 types of instrument discussed?
The 2 types of questionnaire?
What is the difference of the 2 questionnaires?
What is the importance of statistical instrument?
H. Evaluating learning
Make 5 structured and 5 unstructured questions, there should be no repetition of
question, you can no longer write the question that you’ve written in the activity.
The question is related to your studies, your ambitions in life, if ever you have
questions to your family, to your teacher.
Make 5 questions that is answerable by this rating scale:
1 – Strongly Agree
2 – Disagree
3 - Neutral
4 – Agree
5 – Strongly Agree
The questions that you wanted to ask to your favorite character, your showbiz idol,
to someone you’ve been eager to ask questions with.
I.
Additional activities for
remediation/Assignment
Make 5 structured and 5 unstructured questions that you wanted to ask to
your teachers related to the subject they’ve been teaching.
Make 5 questions that is answerable by this rating scale:
1 – Strongly Agree
2 – Disagree
3 - Neutral
4 – Agree
5 – Strongly Agree
The questions that you wanted to ask to yourself.
