Key Concepts in Research Methodology

Key Concepts in Research Methodology

Types of Research

1. Qualitative Research

   • Focuses on understanding concepts, thoughts, and experiences.
   • Methods: interviews, focus groups, observations.

2. Quantitative Research

   • Involves numerical data and statistical analysis.
   • Methods: surveys, experiments, longitudinal studies.

3. Mixed-Methods Research

   • Combines both qualitative and quantitative approaches.
   • Offers a comprehensive perspective on research questions.

Research Design

1. Descriptive Studies

   • Describes characteristics of a population or phenomenon.
   • Often uses surveys and observational methods.

2. Correlational Studies

   • Examines relationships between variables.
   • Does not imply causation.

3. Experimental Studies

   • Involves manipulation of one variable to determine its effect on another.
   • Controlled environments; randomization reduces bias.

4. Longitudinal Studies

   • Observes subjects over an extended period.
   • Useful for studying changes over time.

5. Cross-Sectional Studies

   • Analyzes data from a population at a specific point in time.
   • Provides a snapshot of current conditions.

Sampling Methods

1. Probability Sampling

   • Every member of the population has a known chance of being selected.
   • Types include simple random sampling, stratified sampling, and cluster sampling.

2. Non-Probability Sampling

   • Not all members have a chance of being included.
   • Types include convenience sampling, purposive sampling, and quota sampling.

Data Collection Techniques

1. Surveys

   • Use questionnaires to gather data from participants.
   • Can be conducted online, on paper, or via interviews.

2. Interviews

   • In-depth conversations to explore participants' perspectives.
   • Can be structured, semi-structured, or unstructured.

3. Observations

   • Systematic recording of behavior or phenomena.
   • Can be participant or non-participant observation.

Data Analysis

1. Qualitative Analysis

   • Identifies themes or patterns in textual or visual data.
   • Techniques include coding and thematic analysis.

2. Quantitative Analysis

   • Statistical techniques to interpret numerical data.
   • Includes descriptive statistics, inferential statistics, and regression analysis.

Ethical Considerations

1. Informed Consent

   • Participants must be informed about the research and provide voluntary consent.

2. Confidentiality

   • Researchers must protect participants' privacy and sensitive information.

3. Avoiding Harm

   • Ensure that research does not cause physical or psychological harm to participants.

4. Integrity and Honesty

   • Researchers must report findings truthfully and transparently.

Reporting Research

1. Structure of a Research Paper

   • Abstract, Introduction, Literature Review, Methodology, Results, Discussion, Conclusion.

2. Standard Formatting

   • Follow guidelines for citation and formatting as specified (APA, MLA, etc.).

3. Peer Review

   • Process of evaluation by other experts in the field to ensure quality and validity.

Types of Research

• Qualitative Research focuses on understanding concepts, thoughts, and experiences. Methods include: interviews, focus groups, and observations.
• Quantitative Research uses numerical data and statistical analysis. Methods include: surveys, experiments, and longitudinal studies.
• Mixed-Methods Research combines both qualitative and quantitative approaches to give a comprehensive perspective on research questions.

• Descriptive Studies describe the characteristics of a population or phenomenon. Often uses surveys and observational methods.
• Correlational Studies examine relationships between variables. Does not imply causation.

Sampling Methods

• Probability Sampling gives every member of the population a known chance of being selected. Types include simple random sampling, stratified sampling, and cluster sampling.
• Non-Probability Sampling does not guarantee that all members have a chance of being included in the sample. Types include convenience sampling, purposive sampling, and quota sampling.

Data Collection Techniques

• Surveys gather data from participants using questionnaires via online, paper, or interviews.
• Interviews are in-depth conversations to explore participants' perspectives. These can be structured, semi-structured, or unstructured.
• Observations systematically record behaviors or phenomena. Participant and non-participant observation are two methods.

Data Analysis

• Qualitative Analysis identifies themes or patterns in textual or visual data. Techniques include coding and thematic analysis.
• Quantitative Analysis uses statistical techniques to interpret numerical data. Techniques include descriptive statistics, inferential statistics, and regression analysis.

Ethical Considerations

• Informed Consent requires participants to understand the research and voluntarily agree to participate.
• Confidentiality requires researchers to protect the privacy and sensitive information of participants.
• Avoiding Harm ensures that research does not cause physical or psychological harm to participants.
• Integrity and Honesty requires researchers to report findings truthfully and transparently.

Reporting Research

• Structure of a Research Paper: Includes abstract, introduction, literature review, methodology, results, discussion, and conclusion.
• Standard Formatting: Follows guidelines for citation and formatting as specified (APA, MLA, etc.).
• Peer Review: Process of evaluation by other experts in the field ensures quality and validity of research.
