Study Notes
Quantitative vs Qualitative in Research
Research Design
-
Quantitative Research:
- Structured approach.
- Focus on testing hypotheses and measuring variables.
- Often employs experimental or correlational designs.
- Aims for generalizability across larger populations.
-
Qualitative Research:
- Flexible and exploratory.
- Focuses on understanding meanings and experiences.
- Typically uses case studies, interviews, or participant observation.
- Aims for depth of understanding rather than generalizability.
Data Collection Methods
-
Quantitative Methods:
- Surveys with closed-ended questions.
- Experiments with controlled variables.
- Use of existing databases or secondary data analysis.
- Standardized instruments to ensure uniformity.
-
Qualitative Methods:
- In-depth interviews and focus groups.
- Open-ended questions to elicit detailed responses.
- Observation and ethnographic studies.
- Content analysis of text or visual materials.
Data Analysis Techniques
-
Quantitative Analysis:
- Statistical methods (e.g., regression analysis, ANOVA).
- Use of software for data analysis (e.g., SPSS, R).
- Presentation of data through graphs and charts.
- Focus on numerical relationships and patterns.
-
Qualitative Analysis:
- Thematic analysis to identify patterns and themes.
- Coding of responses to categorize data.
- Narrative analysis to interpret stories and experiences.
- Use of software for qualitative data (e.g., NVivo).
Interpretation Of Results
-
Quantitative Interpretation:
- Results interpreted through statistical significance.
- Emphasis on numerical data and correlations.
- Findings can be generalized if sample is representative.
-
Qualitative Interpretation:
- Results interpreted through context and meaning.
- Emphasis on individual experiences and perspectives.
- Findings are often context-specific and not generalizable.
Validity And Reliability
-
Quantitative Validity & Reliability:
- Validity ensures the instrument measures what it intends to.
- Reliability ensures consistency of results across time and contexts.
- Methods include pilot testing and statistical reliability tests.
-
Qualitative Validity & Reliability:
- Trustworthiness evaluated through credibility, transferability, dependability, and confirmability.
- Strategies include triangulation, member checking, and rich descriptions.
- Focus on the authenticity of findings rather than numerical consistency.
Research Design
- Quantitative research utilizes a structured approach, focusing on hypothesis testing and variable measurement.
- It often involves experimental or correlational designs, aiming for results that can be generalized to larger populations.
- Qualitative research is more flexible and exploratory, seeking to understand meanings and experiences from participants’ perspectives.
- Common qualitative methods include case studies, interviews, and participant observation, emphasizing depth over generalizability.
Data Collection Methods
- Quantitative data collection includes surveys with closed-ended questions, controlled experiments, and analysis of existing data sets.
- Standardized instruments are used in quantitative research to ensure uniformity in responses.
- Qualitative methods consist of in-depth interviews and focus groups that utilize open-ended questions, enabling detailed participant responses.
- Observational techniques and ethnographic studies also play a role in qualitative research, alongside content analysis of written or visual materials.
Data Analysis Techniques
- Quantitative analysis employs statistical methods such as regression analysis and ANOVA to interpret numerical data.
- Software tools like SPSS and R are commonly used for analyzing quantitative data, which is often presented in graphs and charts.
- Qualitative analysis focuses on identifying patterns and themes through thematic analysis, coding responses, and narrative interpretation.
- Qualitative data analysis may also involve software like NVivo to enhance data organization and insight extraction.
Interpretation Of Results
- Quantitative results are interpreted based on statistical significance, emphasizing numerical data trends and correlations.
- Findings from quantitative research can be generalized, provided the sample is representative of the broader population.
- In contrast, qualitative results are interpreted within their specific context, centering on individual experiences and perspectives.
- Qualitative findings are often context-specific, limiting their generalizability compared to quantitative findings.
Validity And Reliability
- In quantitative research, validity ensures that measurement instruments accurately assess what they intend to, while reliability guarantees consistent results over time and across contexts.
- Techniques such as pilot testing and statistical reliability evaluations are used to support the validity and reliability of quantitative studies.
- Qualitative validity and reliability focus on trustworthiness, assessed through criteria such as credibility, transferability, dependability, and confirmability.
- Qualitative approaches may employ triangulation, member checking, and comprehensive descriptions to enhance the authenticity of findings instead of numerical consistency.
