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.

🔍 Exploratory Sequential Research Design

This paragraph introduces the concept of exploratory sequential research design in mixed methods research. It explains that the process begins with qualitative research, such as in-depth interviews or key informant interviews, followed by a quantitative methodology. The qualitative phase aims to explore a specific research issue, and the findings are then generalized through a quantitative approach, such as a survey. The participants in the qualitative phase are distinct from those in the quantitative phase. The paragraph also touches on the use of sample size formulas or calculators to determine the number of participants for the qualitative and quantitative phases. Common goals for using this design include instrument development, generalizing qualitative findings, and employing exploratory factor analysis to extract dimensions or underlying factors from the research issue.

Keywords

💡Mixed Methods Research Design

Mixed Methods Research Design is an approach that combines qualitative and quantitative research methods within a single study. It aims to provide a comprehensive understanding of a research problem by leveraging the strengths of both methodologies. In the context of the video, this design is exemplified by the exploratory sequential research where qualitative research is followed by quantitative research, enhancing the depth and breadth of findings.

💡Exploratory Sequential Research

Exploratory Sequential Research is a specific type of mixed methods research where qualitative research is conducted first to explore a topic in depth, followed by quantitative research to expand or generalize the findings. The video script describes this process, starting with qualitative data collection like in-depth interviews and then moving to quantitative data collection through surveys to generalize the initial findings.

💡Qualitative Research

Qualitative Research is a method of inquiry that focuses on understanding social or cultural phenomena in depth and from the perspective of the participants. It often involves non-numerical data like interviews, observations, and texts. In the script, qualitative research is mentioned as the starting point for collecting data through in-depth interviews to explore specific research issues.

💡Quantitative Research

Quantitative Research involves the collection and analysis of numerical data to test hypotheses and draw statistical conclusions. It is often used to generalize findings from a smaller sample to a larger population. The video script refers to quantitative research as the second phase in the exploratory sequential design, where a survey is conducted to generalize the qualitative findings.

💡In-Depth Interview

An In-Depth Interview is a qualitative research method where the researcher engages in a detailed conversation with an individual to explore their experiences, beliefs, or attitudes. The video script uses this term to illustrate the initial qualitative data collection phase, where such interviews are conducted to understand a particular research issue.

💡Key Informant Interview

A Key Informant Interview is a type of qualitative research where the researcher interviews a person who is knowledgeable about a particular subject or community. This method is mentioned in the script as a way to gather qualitative data that can later be generalized through quantitative methods.

💡Generalization

Generalization in research refers to the process of extending the findings from a study to a larger population or broader context. The video script discusses generalizing qualitative findings by using quantitative methods such as surveys, which allow for a wider application of the initial insights.

💡Sample Size

Sample Size is the number of subjects or observations included in a study. It is crucial for ensuring the validity and reliability of quantitative research. The script mentions the computation of sample size for both qualitative and quantitative phases, emphasizing the need for a systematic approach to determine the number of participants or respondents.

💡Sample Size Calculator

A Sample Size Calculator is a tool used to determine the appropriate number of participants for a study based on factors like desired confidence level and margin of error. The video script refers to using such a calculator or formula to determine the final number of samples for the quantitative phase of the research.

💡Instrument Development

Instrument Development is the process of creating tools or questionnaires for data collection in research. The script mentions this as a common example of an explanatory sequential design, where qualitative findings are used to develop a survey instrument for quantitative data collection.

💡Exploratory Factor Analysis

Exploratory Factor Analysis is a statistical technique used to identify underlying factors or dimensions in a set of variables. The video script describes its use in research to extract significant statements from the qualitative phase and develop a survey questionnaire, which helps in determining underlying factors related to the research issue.
