Study Notes

Quantitative Research Overview

Employs statistical, mathematical, or computational methods to analyze data.
Data expressed in numerical forms, emphasizing objectivity.
Aims to explore relationships between different variables.

Characteristics of Quantitative Approach

Research questions are clearly defined to ensure focus.
Facilitates generalization of concepts, prediction of future outcomes, and investigation of causal relationships.
Utilizes structured research instruments, such as questionnaires, for data collection.
Both large sample sizes and representative populations enhance the reliability of results.
Data is presented in various non-textual forms, including tables, charts, and figures.
High reliability allows for replicability of studies.

Types of Quantitative Research Designs

Non-Experimental Research: Establishes associations between variables without manipulation.
- Survey Research: Most common method, utilizing questionnaires and interviews.
- Correlational Research: Assesses relationships between two variables, indicating correlation but not causation.
- Comparative Research: Compares groups based on descriptive data to identify differences.
Experimental Research: Involves manipulation of variables to establish causality.
- True Experimental: Random assignment to conditions, allowing for causal inferences.
- Quasi-Experimental: Lacks random assignment, often used in real-world settings.

Summary of Key Differences

Non-experimental research focuses on associations without intervention, while experimental research requires manipulation of variables for causal relationships.
Non-experimental methods can suggest relationships; however, they cannot prove cause and effect.
