Study Notes
Quantitative Research Overview
- A large population enhances the reliability of data collected.
- Random sampling minimizes bias from researchers in data interpretation.
- Replication of quantitative methods strengthens validity by verifying findings in diverse settings.
Advantages of Quantitative Research
- Objectivity is achieved through numerical data, making results less prone to misinterpretation.
- Larger sample sizes increase reliability, helping confirm or disprove hypotheses.
- Statistical techniques enable complex data analysis, revealing significant characteristics.
- Replicable methods allow for consistent studies across different contexts.
- Experiments control external factors to ensure unbiased results.
Experimental Research Designs
- True Experimental Design: Controls both time-related and group-related threats, offering the highest internal validity.
- Quasi-Experimental Design: Lacks random assignment, allowing for more data collection and often used in evaluating social problems.
- Pre-Experimental Design: Provides the lowest level of internal validity.
Non-Experimental Research Designs
- Involves natural observation of phenomena without external variable introduction, focusing on data collection without treatments.
- Descriptive Research Design: Aims to document and describe situations as they occur, often serving as a foundation for generating hypotheses.
Types of Descriptive Research
- Survey: Captures quantitative descriptions of trends or opinions through various methods (e.g., face-to-face, online).
- Correlational Studies: Analyze relationships and predict patterns using correlation coefficients.
Variables in Research
- Independent Variable: Influences the outcomes; treated as the manipulative factor in experiments.
- Dependent Variable: Displays the effects or outcomes resulting from changes in the independent variable.
Data Types
- Interval Variable: Unique scale with consistent differences but lacks a true zero (e.g., temperature).
- Ratio Variable: Has a true zero, showing complete absence of the measured variable (e.g., weight, age).
Research Implications
- Quantitative research is essential for testing hypotheses, revealing patterns, and establishing causal relationships in studies.
- Attention to variables helps researchers analyze the impact of various factors comprehensively.
