Study Notes
Weaknesses of Quantitative Research
- Category definitions may not align with local understandings, limiting relevance.
- Focus on theory or hypothesis can overlook significant phenomena.
- Results may be overly abstract and general, lacking contextual applicability.
Strengths of Quantitative Research
- Provides reliable and objective findings through systematic methods.
- Utilizes statistical analysis to generalize results from a sample to a larger population.
- Simplifies complex issues by focusing on fewer variables, enhancing clarity in research.
Importance of Quantitative Research
- Emphasizes objectivity, distinguishing itself from qualitative approaches that prioritize personal experiences.
- Examines relationships between variables and establishes cause-and-effect scenarios in controlled settings.
Research Design in Quantitative Research
- Encompasses the strategic framework used to address specific research questions.
- Incorporates established theories and models to guide the study.
Types of Research Designs
- Experimental: Follows a structured protocol to investigate relationships through typically controlled scientific methods.
- True Experimental: Allows manipulation of independent variables with random assignment to enhance validity.
- Quasi-Experimental: Involves natural settings with non-randomized participant assignment.
- Causal-Comparative: Explores cause-and-effect relationships between independent and dependent variables.
- Non-Experimental: Observes phenomena without manipulating independent variables, focusing on the context of occurrence.
Key Characteristics of Quantitative Research
- Conducted in controlled settings, facilitating the study of large subject groups.
- Follows a systematic method of data gathering before analysis.
- Employs standardized numerical data collection techniques to ensure consistency and replicability of findings.
- Prioritizes testing and validating pre-constructed theories and hypotheses prior to data collection.
