EXPLORATORY SEQUENTIAL MIXED METHOD RESEARCH DESIGN

Summary

The video script discusses the exploratory sequential research design in mixed methods research. It explains that researchers begin with qualitative research, such as in-depth interviews, followed by quantitative methods like surveys. This sequence allows for the generalization of initial findings. The script also highlights the importance of using sample size formulas for quantitative phases and mentions instrument development and exploratory factor analysis as common applications of this research design.

Takeaways

• 🔍 Exploratory Sequential Research Design is a mixed method where qualitative research precedes quantitative research.
• 📝 Qualitative data collection and analysis are conducted first, followed by quantitative data collection and analysis.
• 🗣️ An example of qualitative research could be in-depth interviews or key informant interviews on a specific issue.
• 📊 To generalize findings, a survey might be conducted after the qualitative phase to reach a broader group of respondents.
• 🧑‍🤝‍🧑 Participants in the qualitative phase are typically different from those in the quantitative phase.
• 📐 Qualitative sample size may rely on purposive selection, while quantitative sample size requires a calculator or formula.
• 🛠️ Explanatory Sequential Design is often used for instrument development, allowing researchers to create surveys based on qualitative insights.
• 🔑 A common goal is to extract dimensions or factors from qualitative data to understand underlying structures or generalize findings.
• 🔎 Exploratory Factor Analysis might be employed after the qualitative phase to identify key factors from the research issue.
• 📚 The transcript emphasizes the importance of using mixed methods to enhance the depth and breadth of research findings.
• 📈 The design helps in developing a comprehensive understanding by combining the strengths of both qualitative and quantitative research approaches.

Q & A

What is the mixed method research design mentioned in the transcript?

The mixed method research design mentioned is the exploratory sequential research design, where research begins with a qualitative approach followed by a quantitative methodology.

What is the order of data collection and analysis in an exploratory sequential research design?

In an exploratory sequential research design, qualitative data collection and analysis precede the quantitative data collection and analysis.

Can the participants in the qualitative phase be the same as those in the quantitative phase in this research design?

No, the participants in the qualitative phase are different from those in the quantitative phase in an exploratory sequential research design.

What is an example of a qualitative research approach mentioned in the transcript?

An example of a qualitative research approach mentioned is conducting in-depth interviews or key informant interviews on a particular research issue.

Why might a researcher choose to follow a qualitative approach with a quantitative methodology?

A researcher might choose this approach to generalize the findings from the qualitative research through a quantitative survey to a larger group of respondents.

What is the purpose of using a sample size calculator or formula in the quantitative phase?

The purpose is to determine the final number of samples to be used in the study, ensuring the quantitative research is statistically valid.

What is the common goal of conducting an exploratory sequential research design according to the transcript?

The common goal is to develop an instrument, generalize qualitative findings, extract dimensions or factors, and determine underlying factors from specific research issues.

What is an example of a situation where an exploratory sequential research design might be used?

An example is when a researcher conducts a qualitative phase to understand significant statements and then develops a survey questionnaire to generalize these findings among a larger group.

How can qualitative data be used to inform the development of a quantitative instrument?

Qualitative data can inform the development of a quantitative instrument by extracting significant statements or themes that can be translated into survey questions or items.

What is exploratory factor analysis and how does it relate to the sequential research design?

Exploratory factor analysis is a statistical technique used to identify underlying factors or dimensions within a set of variables. In the context of sequential research design, it can be employed after the qualitative phase to analyze quantitative data and extract relevant factors from the research issue.

Why might a researcher rely on purposive sampling for the qualitative phase?

A researcher might rely on purposive sampling to select participants who can provide rich, in-depth information on the research issue, which is crucial for the initial qualitative exploration.
