Introduction to Research - Qualitative and Quantitative Research and Mixed Method

Summary

This video explores different research methods, comparing quantitative, qualitative, and mixed methods. Quantitative research follows a positivist approach, using large samples and measurable data to test hypotheses, like polling during elections. Qualitative research, on the other hand, uses smaller samples, focusing on in-depth exploration through words and images, often to generate hypotheses without generalizing results. Mixed methods combine both approaches, guided by the research question itself, ensuring the most suitable method is used to answer it. The video emphasizes the importance of choosing the right method based on research goals.

Takeaways

• 😀 Quantitative research follows a positivist philosophy, focusing on scientific observation and hypothesis testing.
• 😀 Researchers collect measurable data in quantitative research to either prove or disprove hypotheses.
• 😀 One advantage of quantitative research is its ability to use larger sample sizes, which can represent broader populations.
• 😀 An example of quantitative research is election polling, where a sample group is used to predict election outcomes.
• 😀 Qualitative research uses an exploratory approach, focusing on deeper understanding rather than measurable data.
• 😀 Qualitative research tends to focus on smaller sample groups to allow for a more in-depth analysis of a subject.
• 😀 In qualitative research, words and images are used instead of numbers to explore a topic.
• 😀 Qualitative researchers typically avoid making broad generalizations based on their findings.
• 😀 Mixed methods research combines both quantitative and qualitative approaches to offer a comprehensive view.
• 😀 Mixed methods research follows a pragmatic approach, where the type of research chosen depends on the research question.
• 😀 The research question itself can often indicate whether a quantitative or qualitative approach is best suited for the study.

Q & A

What is the main philosophy behind quantitative research?

Quantitative research follows a positivist research philosophy, which is based on a scientific approach where the researcher observes objectively in an attempt to prove or disprove their hypothesis.

How is data collected in quantitative research?

Data in quantitative research is collected in a way that it can be measured, often using large sample groups that represent a larger population.

Can you provide an example of quantitative research?

An example of quantitative research would be election polling, where a sample group is used to represent the larger population, and specific questions are asked to measure public opinion.

What is one of the main advantages of quantitative research?

One key advantage of quantitative research is its ability to use larger sample sizes, making it possible to generalize findings to a larger population.

How does qualitative research differ from quantitative research?

Qualitative research is more exploratory, aiming to generate a deeper understanding of a subject, often focusing on smaller sample groups and using words and images rather than numbers.

What is the focus of qualitative research?

Qualitative research focuses on understanding particular people, places, or groups and developing a hypothesis rather than proving or disproving it.

What type of data is used in qualitative research?

Qualitative research uses non-numerical data, such as words and images, to gather deeper insights into the subject being studied.

What is the primary approach of mixed methods research?

Mixed methods research combines both quantitative and qualitative approaches, taking a pragmatic stance where the type of research used is based on what best answers the research question.

How does a research question influence the choice of research method?

A research question can indicate whether quantitative or qualitative research methods should be used. For example, terms like 'measure' suggest quantitative research, while terms like 'explore' suggest qualitative research.

Do qualitative researchers make generalizations from their findings?

No, qualitative researchers generally prefer not to make generalizations based on their findings due to the smaller sample size and the nature of the research.
