Study Notes

Research Design

Research design is the overall strategy for integrating study components logically. It guides the research process.
A well-defined design ensures valid, reliable, and generalizable findings.
Different designs suit various research questions and objectives. Qualitative designs are suitable for exploratory studies, while quantitative designs are better for hypothesis testing.

Qualitative Research Methods

Qualitative methods explore social phenomena, experiences, and perspectives.
Data collection includes interviews, focus groups, ethnography, and observations.
Qualitative research generates rich, descriptive data for nuanced insights.
Common designs are phenomenological, grounded theory, ethnographic, case study, and narrative approaches, each focusing on different insights.

Quantitative Research Methods

Quantitative methods use numerical data and statistical analysis to measure relationships between variables.
Data collection methods include surveys, experiments, and secondary data analysis.
Quantitative research aims to establish cause-and-effect relationships and generalize findings.
Key concepts include variables, operationalization, sampling, and statistical significance.

Mixed Methods Research

Mixed methods combines qualitative and quantitative approaches for a comprehensive understanding.
This approach leverages the strengths of both methods.
It's valuable for investigating complex social phenomena from diverse perspectives.
Researchers carefully integrate methods for effective studies.

Sampling Techniques

Sampling selects a subset (sample) from a larger population for study.
Methods include random sampling, stratified sampling, cluster sampling, and convenience sampling.
Careful sampling ensures generalizability.
The method depends on the research question, resources, and population characteristics.

Data Collection Methods

Data collection methods gather information to answer research questions.
Methods include surveys, interviews, focus groups, experiments, observations, and document analysis.
Surveys collect data from many participants.
Experiments establish cause-and-effect relationships between variables.
Observational studies record behaviors and situations systematically.

Data Analysis Techniques

Data analysis organizes, summarizes, and interprets data to draw conclusions.
Qualitative analysis identifies themes, patterns, and meanings.
Quantitative analysis uses statistical techniques to analyze numerical data.
Software supports both qualitative and quantitative analysis.

Ethical Considerations in Research

Ethical considerations are essential throughout research.
Studies must protect participants' rights and well-being.
Ethical principles include informed consent, confidentiality, and anonymity.
Institutional Review Boards (IRBs) assess research proposals' ethical soundness.

Validity and Reliability

Validity measures the accuracy of a research instrument in measuring what it intends.
Reliability ensures the consistency and dependability of research findings.
Both are crucial for robust and trustworthy research.

Research Proposal

A research proposal outlines the entire project, including research questions, design, methodology, and expected outcomes.
It details the process for answering the research questions.
A comprehensive proposal is needed for funding and ethical approval.
