Qualitative Research Direction: Put a tick (/) if it describes the characteristics of a Quantitative Research, and (x) if it describes Qualitative Research. 1. Data is in the form of words, pictures or objects. 2. The data is usually gathered using structured research instruments. 3. It is not based upon numerical measurements and does not use numbers and statistical methods as key research indicators and tools. 4. It tends to be associated with small-scale studies and a holistic perspective, often studying a single occurrence or small number of occurrences/case studies in great depth. 5. The research study can usually be replicated or repeated, given its high reliability. 6. Data are in the form of numbers and statistics, often arranged in tables, charts, figures, or other non-textual forms. 7. Emphasis is on discovery rather than proof. 8. The results are based on larger sample sizes that are representative of the population. 9. It tends to be associated with emergent research design, using a wide range of approaches 10. Researcher has a clearly defined research question to which objective answers are sought. QUESTIONS:  What is a qualitative research?  What is a quantitative research?  How can you identify a quantitative research from a qualitative research? Choose a statement from the short quiz then elaborate. INTRODUCTION (25 MINS) Communicate Learning Objectives (5 MINS) Introduce the following by stating that at the end of the lesson, the learners shall be able to:  Define the meaning of research  Identify the differences of quantitative research from qualitative research  Describes characteristics, strengths, weaknesses, and kinds of quantitative research Task 1: Quantitative vs. Qualitative Research (20 MINS) 1. Divide the class into groups of with three members. 2. Each group will be distributed with a piece of paper with a research title written on it. 3. Each group must identify the type of research applied with justifications. QUESTIONS: • What type of research was applied? “Dreams won’t work unless you do.” Practical Research II (Quantitative Research) GRADE 12 Tuesday and Thursday 7:15 – 9:15 (HUMSS) • What made you think so? Task 2: True or False (15 mins) I. TRUE or FALSE. Say QUANTITATIVE when the sentence is true while QUALITATIVE if the statement is false. 1. In quantitative research, researchers know in advance what they are looking for. _______________ 2. Quantitative research can be easily misinterpreted because it provides numerical data. _______________ 3. Quantitative research puts emphasis on proof, rather than discovery. _______________ 4. Qualitative research requires a large number of respondents. It assumes that the larger the sample is, the more statistically accurate the findings are. ___________________ 5. One characteristics of quantitative research is that its method can be repeated to verify findings in another setting, thus, reinforcing validity findings. _____________________ 6. In quantitative experiments it filters out external factors, if properly designed, and so the results gained can be seen, as real and unbiased. Quantitative research deals in numbers, logic, and an objective stance. Quantitative research focuses on numeric and unchanging data and detailed, convergent reasoning rather than divergent reasoning [i.e., the generation of a variety of ideas about a research problem in a spontaneous, free-flowing manner].         The data is usually gathered using structured research instruments. The results are based on larger sample sizes that are representative of the population. The research study can usually be replicated or repeated, given its high reliability. Researcher has a clearly defined research question to which objective answers are sought. All aspects of the study are carefully designed before data is collected. Data are in the form of numbers and statistics, often arranged in tables, charts, figures, or other nontextual forms. Project can be used to generalize concepts more widely, predict future results, or investigate causal relationships. Researcher uses tools, such as questionnaires or computer software, to collect numerical data. Task 3: Think-Pair-Share 1. With their groupmates, each group will be asked to draw out a piece of paper with the following words and phrases: OBJECTIVE, CLEARLY DEFINED RESEARCH QUESTIONS, STRUCTURED RESEARCH INSTRUMENTS, NUMERICAL DATA, LARGE SAMPLE SIZES, REPLICATION, FUTURE OUTCOMES “Dreams won’t work unless you do.” Practical Research II (Quantitative Research) GRADE 12 Tuesday and Thursday 7:15 – 9:15 (HUMSS) 2. Three (3) minutes brainstorming will be given to each group then after answers will be collected and shared in front of the classroom. CHARACTERISTICS OF QUANTITATIVE RESEARCH 1. OBJECTIVE. Quantitative research seeks accurate measurement and analysis of target concepts. It is not based on mere intuition and guesses. Data are gathered before proposing a conclusion or solution to a problem. 2. CLEARLY DEFINED RESEARCH QUESTIONS. The researchers know in advance what they are looking for. The research questions are well-defined for which objective answers are sought. All aspects of the study are carefully designed before data are gathered. 3. STRUCTURED RESEARCH INSTRUMENTS. Standardized instruments guide data collection, thus, ensuring the accuracy, reliability and validity of data. Data are normally gathered using structured research tools such as questionnaires to collect measurable characteristics of the population like age, socio-economic status, number of children, among others. 4. NUMERICAL DATA. Figures, tables or graphs showcase summarized data collection in order to show trends, relationships or differences among variables. In sum, the charts and tables allow you to see the evidence collected. 5. LARGE SAMPLE SIZES. To arrive at a more reliable data analysis, a normal population distribution curve is preferred. This requires a large sample size, depending on how the characteristics of the population vary. Random sampling is recommended in determining the sample size to avoid researcher’s bias in interpreting the results. 6. REPLICATION. Quantitative methods can be repeated to verify findings in another setting, thus strengthen and reinforcing validity of findings eliminating the possibility of spurious conclusions. 7. FUTURE OUTCOMES. By using complex mathematical calculations and with the aid of computers, if-then scenarios may be formulated thus predicting future results. Quantitative research puts emphasis on proof, rather than discovery. Task 3: Strengths and Weaknesses 1. The class will be shown pool of sentences. 2. They are to assign the sentences whether it is a strength or a weakness of a quantitative research. 3. There are to write the sentences on each column on the board. STRENGHTS OF QUANTITATIVE RESEARCH The advantages of quantitative research includes the following: “Dreams won’t work unless you do.” Practical Research II (Quantitative Research) 1. 2. 3. 4. 5. 6. GRADE 12 Tuesday and Thursday 7:15 – 9:15 (HUMSS) It is objective. The most reliable and valid way of concluding results, giving way to a new hypothesis or to disproving it. Because of bigger number of the sample of a population, the results or generalizations are more reliable and valid. Since it provides numerical data, it can’t be easily misinterpreted. The use of statistical techniques facilitates sophisticated analyses and allows you to comprehend a huge amount of vital characteristics of data. It is real and unbiased. If the research is properly designed it filters out external factors, and so can be seen as real and unbiased. The numerical data can be analyzed in a quick and easy way. By employing statistically valid random models, findings can be generalized to the population about which information is necessary. Quantitative studies are replicable. Standardized approaches allow the study to be replicated in different areas or over time with formulation of comparable findings. Quantitative experiments are useful for testing the results gained by a series of qualitative experiments, leading to a final answer, and narrowing down of possible directions to follow. WEAKNESSES OF QUANTITATIVE RESEARCH The disadvantages of quantitative research are as follows: 1. Quantitative research requires a large number of respondents. It is assumed that the larger the sample is, the more statistically accurate the findings are. 2. It is costly. Since, there are more respondents compared to qualitative research, the expenses will be greater in reaching out to these people and in reproducing questionnaires. 3. The information is contextual factors to help interpret the results or to explain variations are usually ignored. It does not consider the distinct capacity of the respondents to share and elaborate further information unlike the qualitative research. 4. Much information is difficult to gather using structured research instruments, specifically on sensitive issues like pre-marital sex, domestic violence, among others. 5. If not done seriously and correctly, data from questionnaires may be incomplete and inaccurate. Researchers must be on the look-out on respondents who are just guessing in answering the instrument.
