Study Notes
Importance of Quantitative Research
- Quantitative research significantly contributes to solving complex problems and advancing knowledge across various fields.
- Historical examples include vaccine development for diseases like polio and Covid-19, showcasing quantitative research's role in public health.
- Findings from quantitative studies can shape legislation by revealing the need for interventions, such as imposing community quarantines during health crises.
- Quantitative methodologies help clarify relationships between variables, fostering better decision-making.
Applications Across Disciplines
- Social Science: Assesses interventions on group behavior and explores cultural conflicts and economic stability impacts.
- Natural and Physical Sciences: Evaluates product effectiveness and seeks advancements in material science and alternative energy sources.
- Agriculture and Fisheries: Focuses on increasing crop yield and developing disease prevention methods for crops and livestock.
- Sports: Investigates techniques for enhancing athletic performance.
- Business: Analyzes marketing strategies and their effectiveness on sales.
- Arts and Design: Studies the influence of color on architectural space and the effects of music on learning.
Types of Variables in Quantitative Research
- Quantitative Variables: Numeric and measurable; include discrete and continuous variables.
- Discrete Variables: Countable whole numbers, e.g., student numbers.
- Continuous Variables: Fractional values that can be positive or negative, e.g., height and temperature.
- Qualitative Variables: Categorical and non-numeric; include nominal, ordinal, and dichotomous classifications.
- Nominal Variables: Define categories without intrinsic order, e.g., blood type.
- Ordinal Variables: Rank categories with a meaningful order, e.g., cancer stages.
Measurement Levels
- Interval: Meaningful differences between values, with no true zero, e.g., temperature.
- Ratio: Similar to interval but includes a true zero, e.g., height and weight.
Research Topic Development
- Defining a well-structured research problem is crucial for the success of a study.
- Four basic steps to design a research project: choose a broad topic, conduct preliminary research, define the problem, and refine the question.
Scope and Delimitation
- Scope outlines the boundaries of the study, while delimitation specifies what is excluded or included in the research.
- Components include:
- Topic of the Study
- Variables included/excluded
- Research objectives
- Time frame of the study
- Respondents' characteristics
- Data collection methods
Limitations of the Study
- Delimitations are constraints identified before the research begins, while limitations arise during the study’s execution.
- Understanding the difference helps clarify the research focus and applicability of findings.
Research Framework
- A research framework serves as a blueprint that guides the study and shapes research questions.
- It encompasses key concepts and assumed relationships central to the research plan.
