Study Notes
Quantitative Research Overview
- Focuses on collecting and analyzing numerical data, adhering to a confirmatory scientific method.
- Aims to test hypotheses and theories with large samples for generalizability.
Types of Quantitative Research
-
Descriptive Research
- Observes and describes phenomena as they occur naturally.
- Does not involve experimental manipulation; intends solely to describe characteristics of individuals or objects.
- Example: Assessing types and frequency of physical activities among high school students.
-
Correlational Research
- Examines relationships between variables without establishing cause and effect.
- Data is primarily observational.
- Example: Investigating the correlation between physical activity levels and academic performance.
-
Ex Post Facto Design
- Studies relationships after an event has occurred.
- Investigates possible causes of pre-existing phenomena.
-
Quasi-Experimental Design
- Aims to establish cause-and-effect relationships but lacks random selection, which may impact validity.
- Example: Analyzing the impact of unemployment on attitudes toward safety protocols.
-
Experimental Design
- Establishes cause-and-effect relationships through random assignment and treatment interventions.
- Provides more conclusive results compared to other designs.
Characteristics of Quantitative Research
- Objective nature, minimizing subjectivity in findings.
- Research questions are clearly defined and focused.
- Utilizes structured instruments like questionnaires or checklists.
- Data is presented numerically, allowing for statistical analysis.
- Typically involves large sample sizes to enhance reliability and validity.
- Findings can predict future outcomes and verify existing concepts.
- Designed to be replicable for consistency in research.
Learning Objectives
- Define quantitative research.
- Describe the characteristics and strengths/weaknesses of quantitative research.
- Create suitable types of quantitative research for various fields of interest.
Key Topics in Quantitative Research
- Inquiry methodology and principles.
- Comparison between quantitative and qualitative research methods.
- Non-experimental vs. experimental research classifications, including survey research strengths, designs, and ethical principles.
