Quiz and Study Notes: Planning Research and Selecting Methods
Introduction
Planning research and selecting appropriate methods are foundational steps in conducting effective academic and professional investigations. This process ensures that the research is valid, reliable, and aligned with the study’s objectives. Whether in healthcare, social sciences, or education, choosing the right methodology is essential for producing meaningful results.
📌 Key Concepts
Research Planning
Involves identifying a research problem, formulating questions or hypotheses, and designing a strategy to investigate.
Requires understanding the scope, purpose, and context of the study.
Types of Research
Quantitative: Focuses on numerical data, statistical analysis, and measurable outcomes.
Qualitative: Explores experiences, meanings, and perspectives through interviews, observations, and thematic analysis.
Mixed-Methods: Combines both quantitative and qualitative approaches for a comprehensive view.
Research Design
Descriptive: Observes and describes phenomena without manipulation.
Experimental: Tests hypotheses through controlled experiments.
Correlational: Examines relationships between variables.
Longitudinal: Studies subjects over an extended period.
Sampling Methods
Random Sampling: Every individual has an equal chance of selection.
Stratified Sampling: Population divided into subgroups before sampling.
Convenience Sampling: Based on availability and ease of access.
Data Collection Techniques
Surveys and Questionnaires
Interviews and Focus Groups
Observations
Document and Content Analysis
Ethical Considerations
Informed consent
Confidentiality
Avoidance of harm
Institutional Review Board (IRB) approval
Validity and Reliability
Validity: Accuracy of the measurement.
Reliability: Consistency of the results over time.
📚 Tips for Success
Clearly define your research question or hypothesis.
Choose a method that aligns with your objectives and available resources.
Consider ethical implications and obtain necessary approvals.
Use scholarly sources to support your methodology.
Plan for data analysis during the design phase.
🧾 Summary
Effective research begins with careful planning and method selection.
Understanding the strengths and limitations of each method ensures credible results.
Ethical and practical considerations must guide every step of the research process.
A well-designed study contributes valuable insights to the field.
