Answers
The first step of the scientific method is to ask a question, describe a problem, and identify the specific area of interest. The topic should be narrow enough to study within the context of a particular test but also broad enough to have a more general practical or theoretical merit.
For many sociologists, the goal is to conduct research which may be applied directly to social policy and welfare, while others focus primarily on refining the theoretical understanding of social processes. Subject matter ranges from the micro level to the macro level.
Like other sciences, sociology relies on the systematic, careful collection of measurements or counts of relevant quantities to be considered valid. Given that sociology deals with topics that are often difficult to measure, this generally involves operationalizing relevant terms.
Key Terms
operational definition: A showing of something — such as a variable, term, or object — in terms of the specific process or set of validation tests used to determine its presence and quantity.
operationalization: In humanities, operationalization is the process of defining a fuzzy concept so as to make the concept clearly distinguishable or measurable and to understand it in terms of empirical observations.
