chairs silently. And also please keep all the things unrelated in our subject. None, ma’am. Who are absent for today? Please look at your seatmate. 2. Motivation Before we start our discussion, let us first talk about the communication life of people. If we’re going to compare our communication life before and now, we can say that our present communication life is more advancement than before, it because of many different forms of technologies madein our new generation that makes the life of the people became easy to communicate with their family and friends. And cellphone is one of the technologies made for the present communication life of the people which can bring anywhere they want. Yes ma’am. Like in your case class, I’ am sure that most of you have a cellphone right? (raising of hands. . .)
And who among you have no cellphone? Ok, for your first activity today since we’re talking about cellphone then I want you to know about the sim card use by your classmate it may be a Touch Mobile, Smart, Talk and Text, Sun Cellular, and Globe, how many times in a month they load their sim, and the person they contact usually, it maybe theirfamily, relatives, friends, classmates, or special someone. I will give you three minutes to do your activity and after three minutes you should already have five respondents. And for those who will have five respondents, then you will receive a point for today’s recitation.
Yes ma’am.
Is that clear? Ok, you may now stand and start doing your first activity.

Yes ma’am.
Is that clear?
Ma’am each of us served as the collector of the activity.
And lastly, how will you represent yourselves as part of the activity?

That’s right! In the statistics based from the activity, you can call yourself as the researchers who gathered or collect data from any sources.
Yes ma’am.

this topic?
Ok, good expectation. Now let us start discussing about collection of data by defining the word collection and the word data. Let us first define the word collection. Collection is the act or process of getting things from different places and bringing them together. So it is the literal meaning of collection. Now, how will you define collection in Statistics?
That’s right! Next, let us define the word data.
Ma’am collection is the process of gathering data from different sources and analyzes them together.
Data can be information, statistics, numbers, facts, figures, and records

that used usually to calculate, analyze, or plan something. Now, after we define collection and

collecting some important information.
Yes?
That’s right! So data collection is the process of preparing and gathering information and it is systematic gathering of data for a particular purpose from various sources, which has been systematically observed, recorded, organized. In short, we can say that data collection is a term used to describe a process of preparing and

we gathered not exactly from the primary sources. Ma’am maybe we called that as secondary sources.
If we gathered data not from the primary sources, then what do we called to the sources of the secondary data? That’s right!
Now, like what you said before, the definition of primary data is information gathered directly from the source or we called this data as first-hand or original sources. While secondary data is information gathered from the secondary
sources, such as books, journals, magazines, or thesis of other researchers.
Ma’am because when we gathered data with the use

directly from the source, while secondary data is the
information gathered indirectly from the source. Very good! Just remember that a common classification between primary and secondary data is based upon who collected the data. Yes ma’am. Is that clear? Collecting data is important because itanswers questions whose answers are not immediately obvious;it describes social or physical phenomena in the world around us, and it identify questions for further investigation.
Ma’am it serves as an Now, as a student or as a learner

data which are relevant to what we need in our study.
Ok, good. Now, since we already know how important collecting data is, then for us to develop our knowledge about gathering some important
data then we need to know some important ways on how to collect data. Therefore our discussion will also tackle about different methods of gathering data. Interview Observation Experimentation Questionnaire Registration or Census Interview, observation, experimentation, and questionnaire are the methods of gathering data which can be used to gather primary data.
While registration or census is the method among the given five methods of gathering data that can be used to gather secondary data. Before we discuss each of the methods, I want you to watch first the video that I found that can help you to understand each of the given methods.

Ok, very good observation. And what kind of data have you

seen on the video? Why is it primary data?
Ma’am because the data was gathered directly from the sources.
Very good! Now, let’s define each of the methods of gathering data. First is the interview method. Interview method is a direct method of gathering data because the data was came directly from the source. And since it is directly from the primary source, then this method is a face-to-face inquiry with the respondent.
Like what you have watched from the video, two students gathered data about the importance of the trash can inside their campus by directly asking some of the students of their school. (students will give example) Can you now give another example of gathering data with the use of interview method? Very good class! None ma’am. Now, do you have any questions about interview method? Ok, next is the observation method. This method makes use of the different human senses in gathering information. Ma’am the sense of sight. Now class based from the video and your answer before,which of the human senses use to gathered data as observation method? Ma’am because they Why the sense of sight?
observe the behavior of the students regarding the cleanliness of their school surrounding by looking at the reactions of each students toward the trash that they use to test the
students response.
That’s right! But aside from the sense of sight, we can also use other different human senses to this method it depends only on the data needs to gather by the researcher. Other example for this method is an astronomer looking at the night sky and recording data regarding movement and brightness of the objects he sees, a botanist recording daily data on plant growth after looking and measuring each day, and a doctor watching a patient’s reaction to medication. (students will give example) Now who among you can give another example of gathering data for the observation method? Very good class! None ma’am. Now, do you have any questions about observation method? Now, we proceed to the experimentation method. This method is usually conducted in laboratories where specimens are
subjected to someaspects of control to find out cause and effect relationships. From the video you are right to say that from the first part of the gathering data we can also say that they also use the experimentation method because like a scientist who uses different scientific tools in the laboratories can also do outside the laboratory or anywhere with the use of any materials that can help researchers to analyze the data that they need to gathered. (students will give Now, who among you can also give
examples)
some examples of gathering data with the use of experimentation method? Very good class! Now do you have any questions
None ma’am.
about experimentation method? Next, we proceed to the method of questionnaire. Before we go to the definition of this method, I wantyou todiscover

looking at these pictures.
Now, based from the pictures, what

method a researcher gathered data directly from the person they use as the source of information, while the questionnaire method use some questions written on the paper which not directly gathered from the source.
And what is the similarity of these two methods?
Ma’am the similarity is that the information that we can gathered with the use of these methods is a primary data which came directly from the primary source.
Very good! Now, questionnaire method is referred to as the indirect method of gathering data because this makes use of written questions to be answered by the respondent.
For example is that the government wants to know if people are pleased with how the government is being run, so they hand out questionnaires to the public asking if they are happy and, if not, how to improve. For this example we can say that the data to be gathered is about the satisfaction of the community from the government services. Now, who among you can give

about questionnaire method? Ok, for the last method. We also have the registration or census method. Like in questionnaire method, I will

of this method by also looking at the given pictures.
Now based from the given pictures,
Ma’am the data that can be

not directly from the source.
How did you say so? Ma’am because from the word census, I conclude that the data gathered by the researcher covers the entire record of one country, therefore it means that the data needs can only gathered with the use of some records made by the other sources from the different officials ofone Very good!
society.
Now this method requires the enactment of law to take effect because it needs the participation of a large, if not the entire, population. For example, Educational Characteristics, Number of Live Births by Teenage Mother in the Philippines within 2000-2010, Number of registered deaths, and 2010 Resident Population of United States. Who among you now can give another example of gathering data
(students will give example)
with the use of registration or census method? Very good class!
Now, do you have any questions
None ma’am.
about registration or census method? So do you understand about the
Yes ma’am.
different methods of gathering data? Ok, very good class! C. Generalization Now, let’s have some recap about the terms that was discussed a while ago. What do we mean by data collection?
Ma’am data collection is the process of gathering information from different sources. Ma’am primary and

What types of data can we collect by using these methods?
interview, observation, experimentation, and questionnaire methods, and secondary data is the information that we can collect from the registration or census method. None ma’am.
Very good! Now do you have any questions about collection of data? D. Evaluation Now, for your next activity, I want you to collect data outside the classroom. For this activity, you’re going to gather information with the application of our lesson from the school staff it maybe from the school vendor, security guard, nurse, librarian, or housekeeping. I will give you ten minutes to
gathered data and after ten minutes you’re going back inside the classroom with at least three respondents so you may use your watches to time your activity, and you will do this activity by partner, so you may choose your own partner to gathered data. Now, please fall in line with your partner and before you start I will first give you an activity sheet. (the teacher will distribute activity sheets) Yes ma’am. Ok, in doing your activity please maintain your discipline, no one could make unnecessary noise, is that clear? Ok, you may now start.
(students will start doing the activity)
(the teacher will facilitate the activity) After ten minutes. Ok, class time’s up. Now pass your output, and please go back to your classroom and sit on your proper place, then we will talk about your assigment.
E. Assignment (Review about
(students will pass their output and they will go back to their classroom)
Angles) Now for your assignment I want you to make a survey in your community or in school to find out how far students travel to come to school. Make the best estimate using kilometers, ask at least 40 students. You will do this assignment by group, so now count one to five for you to have a groupmates. You may divide the number of respondents so that each of the members of the groups will have a task for your assignment. And put your assignment on a short bond paper, then you will pass it as a group. Is that clear? Now before we end our class, do you have any questions or clarification regarding your assignment? Ok, that’s all for today. Thank you and good day.
Comment:
Yes ma’am. None ma’am.
Good day ma’am and thank you very much.
