Study Notes
Definition of Research
- Originates from French words: "cerchier" meaning to search intensively, and "recherché" meaning to search closely.
- Combination of "re-" (again) and "search" (to look for); signifies the process of seeking information anew.
Objectives of Research
- Aims to answer questions and acquire new knowledge.
- Contributes to solving problems or clarifying confusing facts.
- Involves systematic investigation through data collection, analysis, and interpretation.
Characteristics of Research
- Logical: Based on valid procedures and principles.
- Cyclical: Begins with identifying a problem and ends with new inquiries.
- Methodical: Follows a structured process.
- Analytical: Breaks information into categories for conclusions.
- Critical: Evaluates assumptions and evidence thoroughly.
- Replicable: Can be repeated under similar conditions.
Scientific Method in Research
- Question: Originates inquiry; must be realistic and answerable through investigation.
- Hypothesis: Educated guess explaining phenomena; testable for prediction.
- Experiments: Test hypotheses under controlled conditions; ensures accuracy and reliability of results.
- Analyses: Data analyzed statistically to validate findings, minimizing faulty conclusions and increasing replicability.
Main Characteristics of Quantitative Research
- Clearly defined research questions with objective answers.
- Careful study design prior to data collection.
- Generalization of concepts and prediction of results.
- Utilizes questionnaires and research tools for numerical data collection.
Strengths of Quantitative Research
- Results are objective and accurate, minimizing misinterpretation.
- Engages a larger sample size for broader study results and generalization.
- Numerical data are easy to analyze, allowing for effective population generalization.
- Standardized methods enable replication and comparison of studies.
Types of Quantitative Research
- Descriptive Research: Collects data to test hypotheses or describe variables; often involves surveys or observations.
- Correlational Research: Examines relationships between variables without implying causation; identifies trends through statistical measures.
- Casual-Comparative Research: Establishes cause-effect relationships involving independent and dependent variables; often examines demographic impacts.
- Experimental Research: Similar to casual-comparative but includes control over variables with random assignment of participants.
- Quasi-Experimental Research: Investigates causes and effects without experimental control; often studies naturally occurring phenomena.
Descriptive Research
- Involves data collection for hypothesis testing or variable description.
- No initial hypothesis required; developed after gathering information.
Correlational Research
- Measures relationships between two or more quantifiable variables; predicts values without implying causation.
Casual-Comparative Research
- Investigates how independent demographic variables affect dependent outcomes, focusing on established relationships.
Experimental Research
- Measures the influence of controlled independent variables on dependent variables through random assignment.
Quasi-Experimental Research
- Examines effects of variables that cannot be manipulated; typically applied to naturally occurring events and their impacts.
