    Study Notes

    Quantitative Research Types

    • Quantitative research is a means of testing objective theories by examining relationships between variables. (Creswell, 2009)
    • Quantitative research can be either correlational or causal.

    Correlational Research

    • Correlational research identifies relationships between two variables.
    • A correlation is a statistical measure of association between two variables. (Vanderstoep and Johnston, 2009)
    • Correlational research looks at:
      • Whether an association exists between variables
      • The magnitude of the association between variables
      • The direction of the association between variables
    • Example: The relationship between hours of sleep and test scores in students, could show no significant relationship, or higher test scores with more hours of sleep.
    • Application areas include:
      • Psychology (human behavior patterns/associations)
      • Example: Association between social media use and academic performance
      • Economics (relationship between foreign exchange rates and credit rating)
      • Political science (relationship between crime rate and votes garnered by a politician)
    • Important note: Correlation does not imply causation. While a relationship may be identified, it does not prove that one variable causes a change in another.

    Causal Research

    • Causal research focuses on cause and effect relationships.
    • Causation refers to the claim that a change in one variable creates a change in another variable. (Vanderstoep and Johnston, 2009)
    • Example: Examining the cause and effect relationship between a food ingredient and the rate of decay of a food sample, how additional unit of food ingredient leads to faster decay.
    • Application Areas include:
      • Natural Sciences (biology, chemistry, physics)
      • In chemistry, experiments may be conducted to show whether a change in quantity of one substance affects characteristics of another substance.
    • Important note: Research in this area uses specific procedures to test potential cause and effect relationships.

    Survey Research

    • A correlational type of quantitative research.
    • Uses a questionnaire as its main data collection tool.
    • Main components include:
      • Survey design (cross-sectional or longitudinal)
      • Population and sample (general group with similar characteristics, and a subgroup for the survey)
      • Survey instrument (questionnaire with closed-ended questions and specific answers)
      • Data analysis and interpretation (descriptive and inferential analyses for survey results)

    Experimental Research

    • A type of quantitative research aimed at causation.

    • Main components include:

      • Respondents (differentiated into experimental/control groups)
      • Variables (independent and dependent variables)
      • Experimental procedures (pretest, actual intervention, posttest)
      • Instrumentation and materials (tools to record observations during the experiment)
      • Experimental procedures differ (pre-experimental, true, quasi, single-subject designs)
      • Data analysis and interpretation (descriptive and inferential analyses of results)

    • Important Note: Experimental research aims to determine if a cause-and-effect relationship exists between variables. In contrast, survey research is used to identify patterns and associations, but not necessarily causal relationships.
