1. Statistical instruments!

2. Class Rules:

3. OBJECTIVES: At the end of the lesson, the participants are expected to: 1. Identify simple statistical instruments; 2. Formulate simple statistical Instruments. 3. Use simple statistical instruments in daily lives.

4. THE WHEEL OF NAMES link: https://wheelofnames.com/

5. “ w h e e l o f f o rt u n e ” Identify the word being defined in each item.

6. 1.A branch of Mathematics that deals with the collection, organization, presentation, analysis, and interpretation of data. STATISTICS

7. 2. A collection of data from every element in a population. CENSUS

8. 3. Consist of numbers representing counts and measurements. QUALITATIVE DATA

9. 4. A complete collection of all elements to be studied POPULATION

10. 5. These are countable in a finite amount of time. DISCRETE VARIABLE

11. 6. A variable obtained by measuring objects or its attributes CONTINUOUS VARIABLE

12. 7. Descriptive attributes which can be observed but not measured. QUALITATIVE DATA

13. 8. A sample that is chosen so that it is easy for the researcher. CONVENIENCE SAMPLE

14. 9. It is characterized by data that consist of names, labels, or categories only. NOMINAL MEASUREMENT

15. 10. Each member of the population has an equally likely chance of being selected. RANDOM SAMPLE

16. Statistical Instruments - This are devices used by the researcher to gather data.

17. A statistical instrument is any process that aim at describing a phenomenon by using any tool. It is a device used to gather or collect the needed data of a study.

18. Types of Statistical Instruments 1. Researcher –Completed Instruments Statistical instruments specifically filled by the researcher Examples: Rating scales, interview schedules/guides, tally sheets, flowcharts, performance checklists, time and motion logs, and observation forms, are some examples of researcher- completed instruments which are to be filled by the researcher.

19. 2. Subject-Completed Instruments Statistical instruments which are to be filled by the subject of the study or the ones being studied. Examples: Questionnaires, self-checklists, attitude scales, personality inventories, achievement/aptitude tests, projective devices, and sociometric devices are some examples of subject-completed instruments which are to be filled by the subject of the study or the ones being studied. Types of Statistical Instruments

20. Formulating simple Statistical Instruments Data is a collection of facts or information. They may be gathered using the following method: Conducting Surveys Interview method is done when a person solicits information from another person(face to face) Questionnaire is done through the use of printed questions regarding a certain matter.(pen and paper)

21. A Questionnaire is a set of printed or written questions with a choice of answers, devised for the purpose of a statistical study . Survey is a form of a statistical instrument used in investigating the opinions or experiences of (a group of people) by asking them questions.

22. 2 . Observing the outcomes of Data/ Observation- The person who gathers data is what we called the investigator while the person/object being observed is the subject. 3 . Experimentation is used by physicists and behavioral scientists in collecting data. 4. Reading statistical Publication/Registration method -refers to continuous, permanent, compulsory of the recordings of the occurrence of vital events together with certain identifying or descriptive characteristics concerning them.

23. Scenario 1. Charmaine wanted to know if her classmates already submitted necessary forms for scholarship application. What statistical instrument can she use to ensure accuracy of data.

24. Based on the scenario, we can conclude that Charmaine needs to ask her classmates if they already submitted the necessary forms . Due to possible high number of her classmates, she can have a hard time if she directly checked the forms of her classmates one-by-one. Recall that subject completed instrument is a statistical instrument which is to be filled by the subject or the ones being studied.

25. In this case, to save time, Charmaine can use a checklist that is to be filled by her classmates to ensure that each of them already submitted the necessary documents for scholarship application

26. Guides in formulating questions: 1. Be clear, specific, and direct. 2. Use the participant’s vocabulary 3. Walk like a real person and treat the questions like a conversation 4. Ask only one person at a time 5. Practice good grammar 6. Avoid bias and loaded words 7. Start with broad, general questions and progress to specific and harder ones 8. Present all the possibilities e  

27. Activity 1: Accomplish this form honestly: ALL ABOUT ME ! What are the three favorite foods do you like most?___________ What games do you like most!__________ Why?____________________________ Who inspired you most?_______Why ?_________ What is your favorite subject?__________ I love to be called as________. I want to go to_________ with my ________on _________. What is your Motto in life?______ Your Latest Picture Here!

28. What I have learned! Activity 2: Complete the graphic organizer below about survey and questionnaire. STATISTICAL INSTRUMENTS SURVEY QUESTIONNAIRE A questionnaire is a research instrument that consists of a set of questions or other types of prompts that aims to collect information from a respondent. A questionnaire may or may not be delivered in the form of a survey, but a survey always consists of a questionnaire.

29. A class of students gathered data concerning which canteen foods were most often thrown in the garbage. As a result of these efforts, certain items were removed from the regular menu. 1. What do you think did the students do to gather the needed data? 2. How did they know which foods were most often thrown in the garbage? 3. If you were to do the same, how will you do it? Activity 3: What I Can Do ! Read the situation below and answer the following questions that follow.

30. Activity 4: Make Me Organize! From the survey in your community or in school, you find out how far your classmates are travelling from their house to their barangay hall to get their module.(Interview 10 schoolmates) Make the best estimate using kilometer . 2. If you are the RBI secretary in your class, how can you identify the number and names of the Most Engaged Learners in Mathematics every Tuesday.

31. Each learner will type on the chat box their names, address and the distance they are travelling in going to their barangay hall to get their modules. Time of submission is after one hour of the session. NAME ADDRESS DISTANCE FROM YOUR HOUSE TO YOUR BARANGAY HALL(in METER) Make Me Organize!

32. Process Goals for Students 4 3 2 1 Problem Solving and Reasoning Shows a thorough understanding of the problem and connected mathematics ‐ Uses a systematic approach to solve the problem ‐ Shows an understanding of the problem and the mathematics of the problem ‐ Uses a systematic approach to solve the problem Provides a partial solution related to the problem ‐ Provides a partially correct answer Provides no solution or a solution unrelated to the problem ‐ Provides no correct reasoning or justification Representations and Connections     Uses abstract or symbolic representation to record information and solve the problem   Uses appropriate and accurate representation to record information and solve the problem Makes an attempt to construct a representation to organize, and record information from the problem that may be partial or inaccurate ‐ Makes no attempt to construct a representation ‐ Makes no identification of patterns Communication ‐ Uses precise mathematical language to clearly communicate process and thinking ‐ Communicates process and thinking in a sequential, coherent way   ‐ Provides a partial communication of process or thinking   ‐ Shows little or no communication of process or thinking   RUBRICS

33. What do you think is the importance of using Statistical Instruments in Statistics?

34. There are two kinds of Statistics : The kind you look up and the kind you make up! Rex Stout

35. For Cooperating! GOD BLESS!
