Quantitative Research Design - Module 1 provides a basic understanding of quantitative research.

  1. 1. Curriculum Designed by Dorothy Kropf
  2. 2. Instructor: Dorothy Kropf, M.A. Doctoral Student of Education at Walden University Specialization: Educational Technology Area of Interest: Research and Higher Educational Issues Module 1
  3. 3. In a quantitative research design, the researcher poses several hypotheses to analyze the cause and effects of specific variables in order to predict and explain certain phenomenon (Creswell, 2009). Quantitative Research Design
  4. 4. To conduct a study, you must have a theoretical framework. What are you basing your research on? Theoretical Framework
  5. 5. What new questions or observations do you have? Do you want to investigate a phenomenon? Do you want to see if an intervention that worked for a small school will work in a larger school? Deductive Reasoning
  6. 6. Start with a research problem. Deductive Reasoning
  7. 7. Start with a research problem. A research problem is a question that stimulates a response through scientific inquiry. Deductive Reasoning
  8. 8. Quantitative research designs start with observations that need further explanations and theories. They make predictions that can potentially answer the hypotheses. Quantitative Research Design
  9. 9. Quantitative research designs are structurally scientific methods, utilizing deductive reasoning in forms of hypotheses (Price & Oswald, 2009). Quantitative Research Design
  10. 10. The outcomes measured in a quantitative research design are factual and based on data-driven information from specific measurement instrument(s) rather than from perceptions (Frankfort-Nachmias & Nachmias, 2008). Quantitative Research Design
  11. 11. The overarching goal of a quantitative research design is to draw relationships between dependent and independent variables, thereby assisting the researcher in developing generalizations that explain or predict certain phenomenon (Creswell, 2009). Quantitative Research Design
  12. 12. Variables and Unit of Analysis According to Frankfort-Nachmias & Nachmias (2008), “the variable whose changes the researcher wishes to explain is known as the dependent variable, while the variable the researcher thinks induces or explains the change is the independent variable” (p. 49). Quantitative Research Design Wow! My kite flies higher when the wind blows harder!
  13. 13. There are 3 types of measures in quantitative research designs: 1. Nominal 2. Ordinal 3. Interval 4. Ratio Quantitative Research Design
  14. 14. Example of Nominal measures: 01 = Female 02 = Male Quantitative Research Design
  15. 15. Example of ordinal measures: College Education 1=some college courses taken 2=Associates Degree conferred 3=Bachelor’s Degree conferred 4= Master’s Degree conferred 5= Doctoral Degree conferred Quantitative Research Design
  16. 16. Example of Intervals: Test Scores: A: =90-100% B = 80-89% C= 75-79% D= 70-74% F= 69% and below Quantitative Research Design
  17. 17. Types of Quantitative Research Designs
  18. 18. Experimental Design A design in which the researcher controls and manipulates variables to determine cause and effects. Quantitative Research Design
  19. 19. Balanced Experimental Design: allows “equal number of observations” despite of the randomness of the study (University of Texas at Austin, n.d.) Quantitative Research Design
  20. 20. Correlational Research Design: A study that examines the relationship between variables and outcomes. Hypothetical Example: There is a strong correlation (or link) with income and the type of car one drives. Again, this is only hypothetical – the more income a salesperson makes, the nicer his car.... Quantitative Research Design
  21. 21. Quasi-experimental Design: The researcher has control over the selected participants and the selected instrumentation. However, the researcher doesn’t have control over who will be exposed and when will the exposure occur. Quantitative Research Design
  22. 22. Single case research: Continuous study of human behavior over time. Example: an intervention study Quantitative Research Design
  23. 23. Meta-analysis research The researcher studies the aggregation of results with other relevant studies. This type of research usually explores the effectiveness of a specific method (Frankfort-Nachmias & Nachmias, 2008). . Quantitative Research Design
  24. 24. Properties or attributes a researcher would like to identify and measure. Types of variables: • Independent variable • Dependent variable • Control variable Variables
  25. 25. Independent variable is the variable that the Researcher has control over. This means that this variable can be manipulated. IndependentVariable
  26. 26. Is not a variable that a researcher can manipulate. Instead, a dependent variable can be observed and measured as a result of the variations of the independent variable. DependentVariable
  27. 27. A variable that the researcher will keep constant. ControlVariable
  28. 28. • To prepare for module 2: • Review the terminologies in this module then decide on a quantitative study you would like to conduct. • Identify what type of research design it is, what your variables are, and your research questions
