Research Methods

What is the main difference between qualitative and quantitative research?

• Qualitative research focuses on numbers, while quantitative research focuses on words.

• Qualitative research is more objective than quantitative research.

• Quantitative research is more flexible than qualitative research.

• The main difference is that qualitative research deals with non-numeric data, while quantitative research deals with numeric data.

Give an example of a qualitative research method.

• Experimental research

• In-depth interviews

• Survey analysis

• Observational study

What type of data does quantitative research focus on?

• Categorical data

• Qualitative data

• Numerical data

• Descriptive data

Explain the concept of reliability in research.

• Reliability in research is the consistency and repeatability of results, ensuring stable and trustworthy findings.

• Reliability in research refers to the speed of data collection.

• Reliability in research is the ability to manipulate results to fit a desired outcome.

• Reliability in research is not important for drawing valid conclusions.

How can researchers ensure the validity of their qualitative data?

• By conducting surveys only

• By employing methods such as triangulation, member checking, peer debriefing, and maintaining detailed documentation of the research process.

• By ignoring participant feedback

• By using outdated research methods

What are the advantages of using qualitative research?

• Quantitative data analysis

• Limited sample size

• Difficulty in replicating results

• The advantages of using qualitative research include in-depth exploration, understanding of complex phenomena, flexibility in data collection, and the ability to capture rich, detailed data.

Discuss the importance of sample size in quantitative research.

• Statistical power is not affected by sample size in quantitative research.

• Sample size has no impact on result reliability in quantitative research.

• A larger sample size decreases the generalizability of findings.

• The importance of sample size in quantitative research lies in its influence on result reliability, generalizability, statistical power, and effect size detection.

What is the role of a hypothesis in quantitative research?

• The role of a hypothesis in quantitative research is to provide a testable statement that predicts the relationship between variables.

• A hypothesis in quantitative research is used to summarize the findings of the study.

• A hypothesis in quantitative research is unnecessary and should be avoided.

• The role of a hypothesis in quantitative research is to confuse researchers.

How do researchers analyze qualitative data?

• By conducting experiments, surveys, and interviews

• By using statistical software to analyze the data

• By coding, categorizing, and interpreting the data to identify patterns, themes, and relationships.

• By counting, summarizing, and visualizing the data

Compare and contrast qualitative and quantitative research methodologies.

• Qualitative research only involves surveys

• Quantitative research focuses on understanding emotions

• Qualitative research does not involve data analysis

• Qualitative research focuses on understanding human behavior through methods like interviews and observations, while quantitative research involves numerical data and statistical analysis.
