Study Notes
Quantitative Research Overview
- An inquiry approach using numerical data to describe relationships and phenomena in nature.
- Characteristics include controllability, generalizability, objectivity, and replicability.
- Strengths lie in understanding the universe, though it needs complementary qualitative approaches for a full perspective.
Types of Quantitative Research
- Descriptive Research: Focuses on accurately portraying characteristics of a population.
- Comparative Research: Compares two or more groups or conditions.
- Correlational Research: Examines relationships between variables; includes survey research for attitudes and trends.
- True Experimental Research: Investigates cause-and-effect relationships; manipulates independent variables and measures dependent variables.
- Quasi-Experimental Research: Similar to true experiments but lacks random assignment.
Research Tools
- Surveys: Utilize questionnaires to collect numerical data from sampled populations.
- Experimental Setup: Participants divided into experimental (receiving treatment) and control groups.
Variables in Research
- Variables can be independent (manipulated), dependent (measured), mediating, moderating, or extraneous.
- Levels of measurement include categorical (groups) and continuous (scale).
- Understanding variable roles aids in data analysis and interpretation.
Research Writing Phases
- Identifying areas of inquiry is crucial and involves specific steps to outline research purpose and scope.
- The research title summarizes the study scope concisely and should be focused, formal, and grammatically correct.
Research Scope and Limitations
- Scope outlines general study boundaries; limitations account for unforeseeable factors impacting results.
- Delimitation specifies researcher-imposed boundaries for the study.
Research Problem and Questions
- The statement of the problem adds context to the research; it is guided by research questions.
- Types of research questions include descriptive, comparative, evaluative, and explanatory, and must be relevant and measurable.
Hypotheses in Research
- A well-defined hypothesis is crucial and should be falsifiable, predictable, clear, and based on existing knowledge.
- Types include null (no effect) and alternative (indicating effect), with subcategories of directional and nondirectional hypotheses.
- Type I and Type II errors can arise from faulty aspects of the research.
Frameworks in Research
- Conceptual frameworks integrate diverse ideas, guiding the research process.
- Theoretical frameworks are based on existing theories relevant to the study.
- Both frameworks emphasize main constructs and concepts within the research.
Definitions in Research
- Conceptual Definition: Defines concepts theoretically.
- Operational Definition: Specifies how concepts will be measured or identified in practice.
