  • QUALITATIVE AND QUANTITATIVE APPROACHES Research Methods Qualitative Research Quantitative Research
  • Definitions of Qualitative and Quantitative Research
    • Quantitative Research
    • A type of educational research in which the researcher decides what to study, asks specific, narrow questions, collects numeric (numbered) data from participants, analyzes these numbers using statistics, and conducts the inquiry in an unbiased, objective manner.
    • Qualitative Research
    • A type of educational research in which the researcher relies on the views of participants, asks broad, general questions, collects data consisting largely of words (or text) from participants, describes and analyzes these words for themes, and conducts the inquiry in a subjective, biased manner.
    Examples?
  • QUALITATIVE AND QUANTITATIVE APPROACHES Research Methods Qualitative Research Hybrid or Mixed Quantitative Research
    • Qualitative approach
      • Definition
        • is an inquiry approach useful for exploring and understanding a central phenomenon.
      • 2. Purpose:
        • To discover various meanings associated with a phenomenon
          • by studying cases intensively in natural settings and
          • by subjecting the resulting data to analytic induction.
    • Quantitative approach
      • 1. Definition:
        • is an inquiry approach useful for describing trends and explaining the relationship among variables found.
      • 2. Purpose:
        • T o describe and explain features of a reality
            • by collecting numerical data.
            • by comparing data from one individual or group to another individual or group.
            • by subjecting the data to statistical analysis .”

      • Formulate hypothesis or theory
  • 4. Determining the Research Approach
    • Use quantitative if your research problem requires you to
    • Measure Variables
    • Assess the impact of these variables on an outcome
    • Test existing theories or broad explanations
    • Apply results to a large number of people
    • Use qualitative if your research problem requires you to
    • Learn about the views of the people you plan to study
    • Assess a process over time
    • Generate theories based on participant perspectives
    • Obtain detailed information about a few people or research sites .
  • Quantitative Designs and Uses Explaining whether an intervention influences an outcome for one group as opposed to another group Associating or relating variables in a predictable pattern for one group of individuals Describing trends or characteristics for the population of people Intervention Research Non-Intervention Research Experimental Research Correlational Research Descriptive Research
  • Qualitative Designs and Uses Exploring the shared culture of a people group Exploring common experiences of individuals to develop a theory Exploring individual stories to describe the lives of people
    • Other possible types:
    • Historical
    • Discourse Analysis
    Ethnographic Research Grounded Theory Research Narrative Research
  • Could be either… Case Study Action Research Study of an individual or small group of individuals to focus on what variables and relationships are present in that individual case Forming a theory in advance and collecting qualitative observations to quickly see if the theory has any validity or application in a small and preselected population. Study of a small group to get an indication of how the group (or individuals within that group) think about a topic. Focus Group

    • Triangulation

    • Sequential – Exploratory
    • Sequential – Explanatory
  • Qualitative & Quantitative Some differences:
    • Qualitative:
    • Considers the participant’s point of view
    • Describes the participant’s view within a particular setting or context
    • Searches to understand a more complex Central Phenomenon rather than a specific research question or hypothesis
    • Typically uses methods such as interviews, observations and interviews
  • Qualitative & Quantitative Some differences:
    • With Qualitative:
    • The qualitative researcher is not an objective, politically neutral observer
    • The qualitative researcher is an observer of the human condition
    • The meaning of the research is plural, more political and open
    • The project is collaborative and participatory
  • Qualitative & Quantitative Some differences: Quantitative:
    • Tries to be objective and look at things without as much consideration of its context.
    • Attempts to find meaning that is equally applicable to all.
    • Tends to focus on numerical comparisons
    • Tries to isolate any possible intervening or confounding variables and focus on one interaction at a time.
  • Quantitative or Qualitative…. What type of research would you use?
  • Quantitative or Qualitative?
    • A study to investigate the reasons why kids fight on the playground
    • A study to see which minorities do best on a certain IQ test.
