As we have learned in the previous lesson, Statistics is a science that studies data. Hence to teach Statistics, real data set is recommend to use. In this lesson, we present an activity where the students will be asked to provide some data that will be submitted for consolidation by the teacher for future lessons. Data on heights and weights, for instance, will be used for calculating Body Mass Index in the integrative lesson. Students will also be given the perspective that the data they provided is part of a bigger group of data as the same data will be asked from much larger groups (the entire class, all Grade 11 students in school, all Grade 11 students in the district). The contextualization of data will also be discussed.

2. OVERVIEW OF LESSON
As we have learned in the previous lesson, Statistics is
a science that studies data. Hence to teach Statistics,
real data set is recommend to use. In this lesson, we
present an activity where the students will be asked to
provide some data that will be submitted for
consolidation by the teacher for future lessons. Data on
heights and weights, for instance, will be used for
calculating Body Mass Index in the integrative lesson.
Students will also be given the perspective that the
data they provided is part of a bigger group of data as
the same data will be asked from much larger groups
(the entire class, all Grade 11 students in school, all

3. LEARNING COMPETENCIES
At the end of the lesson, the learner
should be able to:
 Recognize the importance of providing
correct information in a data collection
activity;
 Understand the issue of confidentiality of
information in a data collection activity;
 Participate in a data collection activity;
and

4. PRELIMINARI
ES IN A DATA
COLLECTION
ACTIVITY

5. • The class student number is randomly
selected
• It is confidential and should not be shared
to others
• It will be used throughout the semester so
remember your number
• In future data collection activities, use your
number instead of names
CLASS STUDENT NUMBER

6. Why have a CLASS STUDENT
NUMBER?
 In data collection activities, specific identities like
names are not required, especially because people
have a right to confidentiality.
 However, there should be a way to develop and
maintain a database to check quality of data
provided, and verify from respondent in a data
collection activity the data that they provided (if
necessary)
 Class student numbers are meant to identify without
having to know the specific identities.
 This helps protect CONFIDENTIALITY OF

7. • In statistical activities, facts are collected
from respondents for purposes of getting
aggregate information, but confidentiality
should be protected.
• Agencies are mandated to collect data that
is bound by law to protect the confidentiality
of information provided by respondents.
CONFIDENTIALITY

8. • Even market research organizations in the private
sector and individual researchers also guard
confidentiality as they merely want to obtain
aggregate data.
• This way, respondents can be truthful in giving
information, and the researcher can give a
commitment to respondents that the data they
provide will never be released to anyone in a form
that will identify them without their consent.
CONFIDENTIALITY

9. PERFORMING
A DATA
COLLECTION
ACTIVITY

10. • to gather data that could use
for their future lessons in
Statistics.
PLEASE do provide the
needed information to the best
of your knowledge.
PURPOSE

11. CLARIFICATIONS
 CLASS STUDENT NUMBER: This is
the number that you’re provided
confidentially to the student at the start
of the class.
 SEX: This is the biological sex and not
the preferred gender. Hence, you have
to choose only one of the two choices
by placing a check mark (√) at space
provided before the choices.

12. CLARIFICATIONS
 NUMBER OF SIBLINGS: This is the number
of brothers and sisters that you has in your
nuclear or immediate family. This number
excludes you in the count. Thus, if the you
are the only child in the family then you will
report zero as your number of siblings.
 WEIGHT (in kilograms): This refers to your
weight based on the your knowledge. Note
that the weight has to be reported in
kilograms.

13. CLARIFICATIONS
 HEIGHT (in centimeters): This refers to
your height based on your knowledge.
Note that the height has to be reported
in centimeters. In case you know your
height in inches, the value should be
converted to centimeters by multiplying
the height in inches by a conversion
factor of 2.54 centimeters per inch.

14. CLARIFICATIONS
 AGE OF MOTHER (as of her last
birthday in years): This refers to the age
of your mother in years as of her last
birthday, thus this number should be
reported in whole number. In case, the
mother is dead or nowhere to be found,
provide the age as if the mother is alive
or around. A zero value is not an
acceptable value.

15. CLARIFICATIONS
 USUAL DAILY ALLOWANCE IN SCHOOL (in
pesos): This refers to the usual amount in pesos
that you are provided for when you go to school
in a weekday. NOTE: you can give zero as
response for this item, in case you have no
monetary allowance per day.
 USUAL DAILY FOOD EXPENDITURE IN
SCHOOL (in pesos): This refers to the usual
amount in pesos that you spend for food
including drinks in school per day. NOTE: you
can give zero as response for this item, in case

16. CLARIFICATIONS
 USUAL NUMBER OF TEXT MESSAGES SENT IN A
DAY: This refers to the usual number of text
messages that you send in a day. NOTE: you can
give zero as response for this item, in case you do
not have the gadget to use to send a text message
or simply you do not send text messages.
 MOST PREFERRED COLOR: You are to choose a
color that could be considered your most preferred
among the given choices. Note that you could only
choose one. Hence, you have to place a check mark
(√) at space provided before the color you consider
as your most preferred color among those given.

17. CLARIFICATIONS
 USUAL SLEEPING TIME: This refers to the usual
sleeping time at night during a typical weekday or
school day. Note that the time is to be reported
using the military way of reporting the time or the
24-hour clock (0:00 to 23:59 are the possible values
to use)
 HAPPINESS INDEX FOR THE DAY : You have to
choose a response on how you feel at that time
using codes from 1 to 10. Code 1 refers to the
feeling that you are very unhappy while Code 10
refers to a feeling that you are very happy on the
day when the data are being collected.

18. NOW
YOUR 10 MINUTES STARTS

19. CENSUS
 Your responses, when recorded and compiled,
would be an example of a CENSUS.
 the government, through the Philippine Statistics
Authority (PSA), conducts censuses to obtain
information about socio-demographic
characteristics of the residents of the country.
Census data are used by the government to make
plans, such as how many schools and hospitals to
build. Censuses of population and housing are
conducted every 10 years on years ending in zero
(e.g., 1990, 2000, 2010) to obtain population

20. What is PSA?
 Philippine Statistics Authority
 PSA is the government agency mandated to conduct
censuses and surveys. Through Republic Act 10625
(also referred to as The Philippine Statistical Act
of 2013), PSA was created from four former
government statistical agencies, namely: National
Statistics Office (NSO), National Statistical
Coordination Board (NSCB), Bureau of Labor and
Employment of Statistics (BLES) and Bureau of
Agricultural Statistics (BAS). The other agency
created through RA 10625 is the Philippine Statistical
Research and Training Institute (PSRTI) which is
mandated as the research and training arm of the
Philippine Statistical System. PSRTI was created from
its forerunner the former Statistical Research and

21. CONTEXTUALIZAT
ION OF DATA

22. • a collection of facts from
experiments, observations,
sample surveys and censuses,

CAN YOU CONSIDER THIS AS
DATA?

24. Although the collection is composed
of numbers and symbols that could
be classified as numeric or non-
numeric, the collection has no
meaning or it is not contextualized,
hence it cannot be referred to as
data.
WHY NOT?

25. • data are facts and figures
that are presented,
collected and analyzed.
Data are either numeric or
non numeric and must be
contextualized

37. KEY POINTS BEING
DISCUSSED
 Providing correct information in a government data
collection activity is a responsibility of every citizen
in the country.
 Data confidentiality is important in a data collection
activity.
 Census is collecting data from all possible
respondents.
 Data to be collected must be clarified before the
actual data collection.
 Data must be contextualized by answering six W-
questions.
