Study Notes
Hypotheses
- Hypotheses are statements guiding research.
- Null Hypothesis (H0): Assumes no significant difference or relationship. Example: No difference in exam scores between morning and afternoon classes.
- Alternative Hypothesis (H₁ or Ha): Suggests a significant difference or relationship. Example: A difference in exam scores between morning and afternoon classes.
- A hypothesis is an educated guess or prediction.
Criteria for a Good Hypothesis
- Specificity: Clearly defines variables and relationships.
- Testability: Provable or disprovable through data.
- Relevance: Aligns with research goals.
- Originality: Adds new knowledge.
- Measurability: Variables can be quantified.
Research Questions
- Research questions define problems.
- Characteristics of good research questions:
- Clear: Unambiguous.
- Focused: Specific and narrow.
- Measurable: Quantifiable.
- Relevant: Aligns with objectives.
- Feasible: Investigatable within constraints.
Functions of Hypotheses
- Guide data collection.
- Provide a framework for analysis.
- Test theories.
- Identify relationships.
- Support conclusions.
Literature Review
- Reviews existing research on a topic.
Purpose of Literature Review
- Provides context.
- Identifies research gaps.
- Establishes foundation.
- Informs methodology.
- Enhances validity.
Sources of Literature Review
- Academic journals.
- Books and textbooks.
- Conference proceedings.
- Theses and dissertations.
- Government reports.
