Study Notes
Nature of Quantitative Research
- Quantitative research involves the use of numerical data to describe phenomena and infer relationships.
- It is primarily focused on measuring and analyzing variables through statistical methods.
Types of Quantitative Research
- Descriptive Research: Focuses on detailing characteristics of a specific group or phenomenon.
- Exploratory Research: Seeks to explore and understand a problem without providing conclusive evidence.
- Correlational Research: Investigates the relationship between two or more variables to identify patterns or correlations.
- Experimental Research: Tests hypotheses through controlled experiments to establish cause-effect relationships.
Characteristics of Quantitative Research
- Generalizability: Results can be applied to a larger population based on representative sampling.
- Objectivity: Research is conducted without bias; data is observable and measurable.
- Controllability: Researchers can manipulate variables to determine their impact on outcomes.
- Replicability: Other researchers can replicate the study to verify results.
Research Variables
- Independent Variable: The variable that is manipulated or changed to observe effects.
- Dependent Variable: The outcome measured to assess the impact of the independent variable.
- Extraneous Variables: Factors that may interfere with the relationship between the independent and dependent variables.
Hypothesis Testing
- Formulating hypotheses is essential in quantitative research to define operational definitions and predictions.
Strengths of Quantitative Research
- Capable of large-scale studies due to statistical analysis.
- Data can be effectively presented in graphical or tabular formats.
- Objective and measurable results lead to scientific credibility.
Weaknesses of Quantitative Research
- Requires significant time and effort, especially with larger sample sizes.
- Reducing observations to numbers can oversimplify complex phenomena.
Research Design Types
- True Experimental: Randomized samples to identify cause-effect relationships.
- Quasi-Experimental: Similar to experimental research but lacks randomization.
- Non-experimental: Includes descriptive, correlational, and comparative designs.
Data Collection Methods
- Surveys are widely used to gather quantitative data, which can include closed-ended questions for numerical analysis.
Important Definitions
- Causal-Comparative: Also known as causal-comparative research, it compares two or more groups to identify differences.
- Mediating Variable: This intervenes between independent and dependent variables.
- Moderator Variable: Influences the strength of the relationship between the independent and dependent variables.
Notable Researchers
- Creswell has defined quantitative research as a means for testing objective theories through relationships among variables.
- Vanderstoep and Johnston emphasized correlational research as a measure of association between variables.
