A code in research methodology is a short word or phrase describing the meaning and context of the whole sentence, phrase, or paragraph. Important PointsTypes of codingDescriptionsSelective Coding Selective coding refers to the final stage of data analysis to be completed after core concepts emerging from the coded data categories and subcategories have been identified through open and/or axial coding. Selective coding is the culmination of the grounded theory process and its purpose is to either define a new theory or modify an existing theory based on your research. Initial Coding Initial coding, also known as €œopen coding,€ is the first step of the coding process, particularly in qualitative methods such as grounded theory. In this coding, comparing data with data, staying close to and remaining open to exploring what is happening in data, construct and keep the code short, simple, precise, and active. Focused CodingThe objectives of focused coding are to identify recurrent patterns and multiple layers of meaning and to delineate variations and interconnections among sub-themes within the general topic. To discover the most significant or frequent initial code that makes the most analytical sense. Theoretical CodingA theoretical code is a relational model through which all substantive codes/categories are related to the core category. It specifies possible relationships between categories, these are integrative. Thus the correct match is A-II, B ? IV, C ? I, D ? III.
