1. PRACTICAL RESEARCH 2 Nature of Inquiry and Research

2. LEARNING COMPETENCIES describe characteristics, strengths, weaknesses, and kinds of quantitative research ; illustrate the importance of quantitative research across fields ; and differentiate kinds of research variables and their uses . At the end of the discussion, the learner should be able to:

3. INQUIRY VS RESEARCH

4. INQUIRY VS RESEARCH INQUIRY RESEARCH DEFINITION refers to the process of asking questions to gain information, clarify doubts, or explore a topic. It is often the initial stage of investigation where curiosity leads to questioning. is a systematic and methodical process of investigating a specific question, problem, or hypothesis. It involves collecting, analyzing, and interpreting data to draw conclusions. PURPOSE is to gather basic information or understanding. It can be informal and may not necessarily follow a structured method. is to generate new knowledge, validate theories, or solve specific problems. Research is usually more formal and structured, often leading to documented findings or publications.

5. INQUIRY VS RESEARCH INQUIRY RESEARCH SCOPE is broader and less structured, often involving open-ended questions. It can be done on a personal level, in everyday situations, or as a preliminary step in a larger investigation. more focused and structured, often following a specific methodology. It typically involves a clear objective, detailed planning, and rigorous analysis. EXAMPLES Asking questions in a classroom to understand a concept, seeking information from a professional, or exploring a new topic out of curiosity. Conducting experiments in a laboratory, writing an academic paper, or performing a market analysis for a business.

6. RESEARCH ETYMOLOGY: “research” was coined from French word “cerhier” which means “seek” . The prefix “re” means to repeat. Research is to repeat looking or seeking for something. A natural day-to-day activity of gathering information. QUALITATIVE RESEARCH seeks to answer questions about why and how people behave in the way that they do. It provides in-depth information about human behaviour. QUANTITATIVE RESEARCH is “explaining phenomena by collecting numerical data that are analysed using mathematically based methods (in particular statistics).”

9. LESSON 1 CHARACTERISTICS STRENGTHS WEAKNESSES

10. COMPREHENSION CHECK Determine whether INQUIRY or RESEARCH is applicable to the given situations. A person wants to know the occupant of one condominium. A student wants to know the medicinal effects of guava leaves. Mr. Cruz wants to know the technique to make his electric fan function instantly. Aling Rosa wants to know the reason behind the decrease of her sales for the day. Prof. Gomez wants to discover the impact of social networking on his students’ learning abilities. :

11. QUANTITATIVE RESEARCH an objective, systematic empirical investigation of observable phenomena through the use of computational techniques. concerned with numbers and its relationship with events . suggests that the data concerned can be analyzed in terms of numbers .

12. CHARACTERISTICS OF QUANTITATIVE RESEARCH

13. CHARACTERISTICS OF QUANTITATIVE RESEARCH 1. Seeks accurate measurement and analysis of target concepts . The truth cannot be falsify. Objective

14. CHARACTERISTICS OF QUANTITATIVE RESEARCH 2. The researcher has a clearly defined research question to which objective answers are sought. Researchers know in advance what they are looking for Clearly Defined Research Questions

15. CHARACTERISTICS OF QUANTITATIVE RESEARCH 3. The data are usually gathered using more structured instrument to collect measurable data. Standardized Research Instruments

16. CHARACTERISTICS OF QUANTITATIVE RESEARCH 4. Data are in the form of numbers and statistics. Numerical Data

17. CHARACTERISTICS OF QUANTITATIVE RESEARCH 5. The results are based on larger samples sizes that are representative of the population Large Sample Sizes

18. CHARACTERISTICS OF QUANTITATIVE RESEARCH 6. The research study can usually be replicated or repeated, give its high reliability Replication

19. CHARACTERISTICS OF QUANTITATIVE RESEARCH 7. Project can be used generalize concepts more widely, predict future results, or investigate causal relationship Future Outcomes

20. GROUP WORK: Formulate quantitative research questions about the following topics: Food at the school canteen Philippine transportation system Communication media Social networking sites After school 6. Vocabulary 7. Video Game 8. Coping Mechanism 9. Reading Comprehension

21. STRENGTHS AND WEAKNESSES OF QUANTITATIVE RESEARCH

22. STRENGTHS: It is objective. Uses statistical techniques . Quick and easy analysis of data . Quantitative research design is the most reliable and valid way of concluding results. Quantitative studies are replicable.

23. WEAKNESSES: It requires a large number of respondents. It is costly. The information and contextual factors to help interpret the results or to explain variations are usually ignored. Many information are difficult to gather using structured research instruments. If not done seriously and correctly, data from questionnaires may be incomplete and inaccurate.

24. LESSON 2 IMPORTANCE OF QUANTITATIVE RESEARCH ACROSS FIELDS

25. Field Contribution/Application Example Social Science Effects of intervention to group behavior Understanding cultural or racial conflicts Human satisfaction and stressors The effects of pandemic on social behavior and economic stability Natural and Physical Sciences Investigate the effectiveness of a product or treatment to illnesses Finding or enhancing alternative energy sources Advancement in material science Antidiabetic properties of common Philippine herbs

26. Field Contribution/Application Example Agriculture and Fisheries Increase the yield crops Prevention and cure for crops and livestock diseases The effect iveness of organic and inorganic fertilizer to vegetable production Sports Enhance athletic performance Diet and exercise techniques for different kinds of sports Business Device marketing strategies Improve marketability The effect iveness of facebook ads on sales

27. Field Contribution/Application Example Arts and Design Relationship between color and architectural space Multimedia use and adaptation for recreation, business marketing and lifestyle changes The effects of music on learning and behavior Environmental Science Causes and effects of climate change The environmental factor affecting natural calamities
