Do you want that?” “Great! Now we’ll be playing Wheel of Fortune. In this activity, I will be asking you questions about our previous lesson. Whoever the person that corresponds to the number pointed by the wheel of fortune will be the one to answer my questions. Are you ready?” “Very good. So now, let’s get the ball rolling.” ~ Questioning follows. “You really had listened to our previous lesson and it deserves an Aling Dionesia clap.” “Do you have questions regarding our previous lesson?” “Yes, Ma’am.” (Students followed the instruction.) “Yes, Ma’am.” “Yes, Ma’am.” “Yes, Ma’am.” (Aling Dionesia Clap) “None, Ma’am.” B. MOTIVATION “In order for you to have a glimpse of our lesson today, do you want another activity?” “Good! This time, I will be grouping you into 6. You have your group already, right? You will be with the same group. At the count of 5 you have to be in your group and make a circle. 1, 2, 3, 4, 5.” “You will be with group starting now until the end of our class.” “As you can see I have here an envelope containing letters. Each letter corresponds to an answer. Each group is given the task to complete the missing boxes shown by answering numbers 1-10. The answers will be chosen on the letters with the corresponding answer. Whoever group who formed the word first and correctly will be given the points. Am I clear?” “You just have to paste this letters according to the box or number where you “Yes, Ma’am.” “Yes, Ma’am.”
- 3. have your answer. Whenever you are done, just do a yell or the sound of your group and post your output on the board. You are only given 5 minutes to do the activity. Understood?” “Ready na, ready na?” “You can start now.” Answering and giving of points follows. “Yes, Ma’am.” “Aha! Aha!” ~ Questions: 1. 30 + 20 2. 45 - 20 3. 23 4. √9 5. 𝑎0 6. ǀ-11ǀ 7. 1 km = _______m 8. 9. (2,348)(0) 10. 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.

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.” IV. Evaluation Choose the letter of the correct answer. 1. It is the science of collection, organization, analysis, and presentation of data. a.
