Final answer:
Physically vs. socially based coding schemes are part of data collection's coding schemes, with the former focused on observable characteristics and the latter on social constructs. Symbolic interactionists are more likely to use participant observation to understand social interactions.
Step-by-step explanation:
The question regarding physically vs. socially based coding schemes is related to the different methods used in data collection, particularly in the field of social sciences research. These coding schemes are important tools for organizing data so that it can be systematically analyzed. In this context, the correct answer to the question is a) Coding schemes.
Coding schemes are used to categorize and label data that has been collected during the research process. In social research, coding can be based on physical attributes or observable characteristics, which is known as physically based coding. On the other hand, socially based coding involves categorizing data according to social meanings, norms, or other constructs relevant to the study.
With regard to the given reference question, a symbolic interactionist, who focuses on understanding how people create symbolic meanings and social structures through their interactions, would most likely employ b) Participant observation as their research technique. This method allows them to observe and interpret social interactions within their natural context.
