Research Methodologies

What are the key characteristics of qualitative research methods?

• Primarily used for testing hypotheses and theories

• Focus on statistical analysis and numerical data

• Focus on exploring human behavior, emotions, and experiences

• Emphasis on proving cause and effect relationships

Answer explanation

Qualitative research methods focus on exploring human behavior, emotions, and experiences.

Explain the difference between qualitative and quantitative research methods.

• Qualitative research methods are more objective and unbiased, while quantitative research methods are more subjective and opinion-based.

• Qualitative research methods focus on numerical data and statistical analysis, while quantitative research methods focus on understanding human behavior and the reasons behind it.

• Qualitative research methods focus on understanding human behavior and the reasons behind it, while quantitative research methods focus on numerical data and statistical analysis.

• Qualitative research methods use surveys and questionnaires, while quantitative research methods use interviews and observations.

Answer explanation

Qualitative research focuses on understanding human behavior, while quantitative research focuses on numerical data and statistical analysis.

What are the advantages of using quantitative research methods?

• Quantitative research methods provide precise and measurable data, allow for statistical analysis, and can be used to generalize findings to a larger population.

• Quantitative research methods cannot be used to generalize findings

• Quantitative research methods only allow for descriptive analysis

• Qualitative research methods provide precise and measurable data

Answer explanation

Quantitative research methods provide precise and measurable data, allow for statistical analysis, and can be used to generalize findings to a larger population. This is the correct choice because it offers the advantages of precise data, statistical analysis, and generalizability.

Discuss the steps involved in experimental research design.

• Conducting a survey, analyzing the results, and drawing conclusions

• Reviewing literature, identifying the research problem, and collecting data

• Identifying the research problem, reviewing literature, formulating a hypothesis, designing the experiment, collecting and analyzing data, and drawing conclusions

• Interviewing participants, formulating a hypothesis, and designing the experiment

Answer explanation

The steps involved in experimental research design include identifying the research problem, reviewing literature, formulating a hypothesis, designing the experiment, collecting and analyzing data, and drawing conclusions. This choice correctly outlines all the necessary steps.

How is a case study methodology different from other research methods?

• Case study methodology only focuses on quantitative data

• Case study methodology is not suitable for analyzing specific cases

• Case study methodology does not provide detailed analysis

• Case study methodology provides in-depth analysis of a specific case or situation.

Answer explanation

Case study methodology provides in-depth analysis of a specific case or situation.

What are the limitations of using qualitative research methods?

• Subjectivity, difficulty in generalizing findings, time-consuming data analysis

• Lack of creativity in data collection

• Limited sample size

• Inability to measure cause and effect relationships

Answer explanation

Qualitative research methods have limitations such as subjectivity, difficulty in generalizing findings, and time-consuming data analysis.

Explain the concept of sampling in quantitative research methods.

• Sampling involves collecting data from the entire population for research purposes.

• Sampling is the process of selecting a representative group from the larger population for research purposes.

• Sampling is not necessary in quantitative research methods.

• Sampling is the process of selecting only the most extreme cases for research purposes.

Answer explanation

Sampling is the process of selecting a representative group from the larger population for research purposes.

What are the ethical considerations in experimental research design?

• Sharing participants' personal information without consent

• Not obtaining informed consent

• Maximizing harm to participants

• Informed consent, confidentiality, minimizing harm to participants

Answer explanation

Ethical considerations in experimental research design include informed consent, confidentiality, and minimizing harm to participants.

Provide an example of a successful case study and its impact on research.

• The Bermuda Triangle case study

• Phineas Gage case study

• The Bigfoot case study

• The Loch Ness Monster case study

Answer explanation

The Phineas Gage case study is a successful example that had a significant impact on research. It highlighted the effects of brain injury on personality and behavior, leading to advancements in neuroscience.

Discuss the importance of triangulation in qualitative research methods.

• Triangulation in qualitative research helps to increase the credibility and reliability of the research findings.

• Triangulation in qualitative research is a waste of time

• Triangulation in qualitative research only adds confusion

• Triangulation in qualitative research is not important

Answer explanation

Triangulation in qualitative research increases credibility and reliability of findings.
