Study Notes
Research Scope and Delimitations
- Specifies the study's coverage, subject, instruments, issues, and duration.
Research Types
- Descriptive: Observing phenomena.
- Correlational: Investigating variable relationships.
- Experimental: Examining cause-and-effect relationships between two or more variables.
Hypotheses and Research Questions
- Hypotheses predict variable relationships and connect to the research problem.
- Factor-relating questions: Explore relationships among factors (non-experimental research).
- Factor-isolating questions: Isolate, categorize, describe, or name factors and situations.
Defining Terms
- Conceptual definition: From dictionaries or encyclopedias (e.g., GPA as grade points earned divided by total credits).
- Operational definition: Concrete definition for measurement within the study.
Research Preparation
- Familiarize yourself with research terminology.
- Review existing research for relationships and relevance.
- Ensure research question accuracy and relevance.
Citations
- Use APA in-text citation style (e.g., (Jones, 1998, p. 199)).
Hypothesis Types
- Hypothesis: An educated guess.
- Null hypothesis: No significant difference or effect.
- Alternative hypothesis: A significant difference or effect.
Research Example: Effect of Temperature on Plant Pigmentation
- Independent variable: Temperature.
- Dependent variable: Plant pigmentation.
Important Note on Problem Statements
- Avoid including sub-problems, background, conclusions, implications, and recommendations in the problem statement.
Redundancy in Research Titles
- Avoid phrases like "An Analysis of," "An Investigation of," and "The Study of" as they are often redundant.
Extraneous Variables
- Also known as facilitating, mediating, or intervening variables.
Variable Types
- Discrete: Countable (e.g., cars, attendance).
- Continuous: Infinite (e.g., weight, height, price).
- Nominal: Unordered categories (e.g., business types, eye color).
- Ordinal: Ranked categories (e.g., clothing sizes).
Characteristics of Quantitative Research
- Objective, logical, and systematic.
Intervening Variables Example
- In a study on Koi fish survival, water, oxygen, and tank conditions are intervening variables.
Research Framework Components
- Statement of the problem: Contains specific research questions.
- Scope and delimitation: Includes location, respondents, and time.
- Research title: Summarizes the study’s main ideas.
- Research background: Provides historical context and background information.
Research Methods Summary
- Descriptive: Observing phenomena.
- Correlational: Studying variable relationships.
- Experimental: Examining cause-and-effect relationships.
- Conceptual framework: Explains key factors, concepts, or variables.
- Theoretical framework: Uses abstract concepts and relationships to explain and predict observations.
Hypothesis Formulation Guidelines
- Hypotheses should predict the relationship between the research problem and variables.
- A good research title is concise and clear.
- Poor research questions lack significance.
Additional Notes on Hypotheses and Research Discussion
- The CARS model helps structure problem discussion.
- Hypotheses should be declarative statements establishing logical relationships.
Citing Multiple Authors
- For articles with six or more authors, use the first author's name followed by "et al." in the citation.
