This approach allows researchers to triangulate results, validating and enriching the overall conclusions drawn from the study by drawing on the strengths of both data types.
Data coding: Data coding is the process of transforming qualitative or quantitative data into a standardized format that can be easily analyzed and interpreted. This involves assigning numerical or categorical codes to responses or data points to facilitate analysis, particularly in research settings where large datasets are involved. Proper coding allows researchers to identify patterns, trends, and relationships within the data, enhancing the overall understanding of the subject matter.
Exploratory Sequential Design: Exploratory sequential design is a mixed-methods research approach where qualitative data is collected first to explore a phenomenon, followed by quantitative data collection to test or generalize the initial findings. This approach emphasizes understanding a context or issue deeply before quantifying it, allowing researchers to refine their questions and methods based on qualitative insights.
Flexibility: Flexibility refers to the ability to adapt and change methods or approaches in research based on evolving circumstances or new information. This adaptability is crucial when dealing with exploratory sequential designs, allowing researchers to refine their focus, adjust their methodologies, and incorporate findings from initial phases into later stages of the study.
