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
