C. LESSON PROPER
Introduction to the Lesson
“Now based on the activity that we
had a while ago, do have now an idea on
what will our lesson be today?”
“What do you think will our lesson
be today? Yes, ____.”
“Excellent. That’s it. We will explore
now on Statistics. About its definition, uses,
as well as its application to real-life. But
before that, let us first know the objectives
that everyone must attain at the end of the
lesson. Everyone, kindly read.”
~ Reading of objectives.
Discussion
“Looking at what I have here, this is a
tape measure. I want to ask six (8) persons to
volunteer and come here in front. This time,
we will be measuring your arm span, that is
you stretch out both arms and we’ll measure
“Yes, Ma’am.”
“Ma’am, I think our lesson for today will be
about Statistics.”
At the end of the lesson, the students can:
a. Collect or gather raw data and
organize the data according to some
systematic consideration;
b. Distinguish between statistical
questions and not statistical question;
c. Classify statistical question and not
statistical question; and
d. Value the importance of
understanding statistics, connecting it
to daily lives’ activities.
S – 50 I – 1 C - 0
T – 25 S – 11 S - ray
A – 8 T - 1000
T – 3 I – triangle
4. the length from the tip of a middle finger to
the tip of the other middle finger. 7 of you
will be measured while the last one will be
the one to assist me and write the results.”
~ Measuring . . .
“We have now this following results.
~ Possible data depends.
“What do you think these numbers
represent?”
“Correct. These numbers are called the
RAW DATA. Raw data are data which are not
yet sorted or arranged according to some
criteria or some systematic consideration.
“Can we get clear and precise
information immediately as we look at these
numbers?”
“Why do you think so?”
“How can we make these numbers
meaningful for anyone who does not know
about the description of these numbers? In
order for other people to know what these
numbers mean, we need to sort them and
arrange from highest to lowest or from
lowest to highest. When they see it already in
an arranged form, then people can conclude
what these numbers mean. Am I right?”
“Okay, who wants to arrange these
numbers from highest to lowest? Yes,
_____.”
“Now looking at it, is it now easy for
us to think what these numbers mean? It
could mean a lot of things right?”
“In our daily activities, a lot of sorting
and organizing objects, data, or things like
what you just did. These are just few of the
activities of doing Statistics.
“What do we mean by Statistics?”
“When we say STATISTICS that
pertains to the science of collection, analysis,
and presentation of data. Statisticians,
contribute to scientific inquiry by applying
their knowledge to the design of surveys and
experiments; the collection, processing, and
analysis of data; and the interpretation of the
results.”
“There are a lot of examples of
activities wherein Statistics is involved. We
could identify it whether it’s a Statistical
question or not.”
~ Showing of a statistical question and not
statistical question.
(Volunteers do the instruction.)
“Ma’am, these represent the measures of the
arm span of 7 students in this class.”
“No, Ma’am.”
(Answers vary)
“Yes, Ma’am.”
(The student arranged the numbers)
“Yes, Ma’am.”
(Answers vary)
(Students listen attentively.)
Questions:
What time do most people eat their
lunches?
What time did you eat your lunch?
5. “What have you observed on the
following questions?”
“What about the way the questions
are asked?”
“Excellent observation. Indeed, on
the first question, different answers could be
formulated while on the second one, exact
answer will be answered.”
“A statistical question has answers
that will probably vary. Usually, a statistical
question will ask a population of multiple
people, event or things. A statistical question
is a question that should have different
answers.”
Giving of examples and thorough
discussion of statistical questions.
“Opposite to this is not a statistical
question. Once it has an exact answer and
that if it ask one person for one answer, then
that is not a statistical question.”
Giving of examples and differentiation
of statistical and not statistical
questions.
“Ma’am, it’s a question about people eating
lunch.”
“Ma’am, on the first question, its general.
We could answer a lot of ideas to it while on
the second question, it’s like asking one
person, and its answer would be one.”
(Students listens attentively in the
discussion.)
D. GENERALIZATION
“Have you learned a lot with the
discussion today?”
“Really, Cow group? How about the
Monkey group? Snake? Wolf? Bird? Cat?
“Who can say something about what
you had learned?”
“Very good. Group mates of (name of
student), you do your group sound.
“Now, how would you distinguish
between statistical or not statistical
questions?”
“You got it right. You indeed listened
to the discussion. Now, do you find statistics
helpful to us?”
“Why do you think so?”
“You really had listened to our
discussion. Let’s give ourselves a Digong
Clap.”
“Do you questions, clarifications or
additions with regards to our lesson for
today?”
“Yes, Ma’am.”
(Each group do their group sound.)
“Ma’am, this morning, I had learned about
Statistics. Statistics is the science of
collection, analysis, and presentation of
data.”
“Ma’am, a question is statistical if it could be
answered differently and is answered by
multiple. It’s not statistical if it has an exact
answer.”
“Yes, Ma’am.”
(Answers vary)
(Digong Clap)
“None, Ma’am.”
6. E. APPLICATION
“Do you want another activity?”
“At this juncture, I will group you
again. You will still be with your group. We
will be playing a game called “Sort Me Out”. I
have here cut out strips of different
questions. These are either statistical or not
statistical. Each group is given the task to sort
or classify this questions to either it’s
statistical or not. You see this manila paper
with a T-chart? The questions you think is
statistical will be paste on the column for
statistical questions, and those questions
which you classified to be not statistical will
be paste on its particular column. I will give
you a hint to get a high group score. You just
have to analyze it thoroughly and must work
together with your group mates. You are only
given 5 minutes to do the activity. Do you get
me?”
“For the scoring of this activity, we
will be following this criteria.
“After sorting, you immediately do
your group sound to be recognize and post
your output on the board. Am I clear?”
“You can start now.”
~ Presentation of Outputs and giving of
scores.
“Yes, Ma’am.”
CRITERIA FOR SCORING:
Unity and Cooperation – 10 pts.
Correctness – 5 points each item
“Yes, Ma’am.”
