Study Notes
Introduction to Quantitative Research
- Quantitative research utilizes scientifically collected and statistically analyzed data to study observable phenomena.
- Focuses on facts or situations that need deeper understanding or exploration.
Key Aspects of Quantitative Research
- Employs scientific methods to design studies and collect numerical data.
- Data must be numerical and quantifiable to allow for effective statistical analysis.
Numerical Data vs Non-Numerical Data
- Numerical data is easier to collect compared to qualitative descriptions.
- Examples of numerical data include:
- Student grades across subjects.
- Hours of social media engagement among teenagers.
- Consumer preferences for product packaging.
- Covid-19 patient recovery averages by region.
Conversion of Non-Numerical Data
- Non-numerical data can be transformed into numerical form using scales like the Likert scale.
- Rating scales convert qualitative responses into quantifiable numerical data to facilitate mathematical operations.
Characteristics of Quantitative Research
- Large Sample Size: Essential for achieving statistically significant results.
- Objectivity: Data gathering and analysis remain unaffected by the researcher’s opinions.
- Concise Visual Presentation: Numerical data allows for easy visualization through graphs, charts, and tables.
- Faster Data Analysis: Statistical tools streamline the data interpretation process.
- Generalized Data: Sample data can represent the larger population if collected appropriately.
- Fast and Easy Data Collection: Standardized research instruments enable efficient data gathering from large samples.
- Reliable Data: Data collected is seen as credible, aiding in informed decision-making.
- High Replicability: Quantitative methods can be repeated to verify results, enhancing validity.
Advantages of Quantitative Research
- Objective and grounded in numerical data.
- Predictive potential of numerical data on future outcomes.
- Findings applicable to the broader population providing generalizability.
- Establishes clear cause-and-effect relationships.
- Employs statistical techniques for sophisticated analysis.
- Offers quick and straightforward data analysis using valid random sampling.
- Replicable findings enhance reliability and validity.
Disadvantages of Quantitative Research
- Limited exploration of individual experiences or subjective information.
- May overlook contextual factors influencing data.
