Concept Analysis of "Development of Online Friendship in Different Social Spaces"Chris Watson Queens University of CharlotteMass Media Research discusses concepts and constructs in its second chapter. Author, Roger D. Wimmer, thoroughly explains other aspects of a research study, such as types of measurements, variables, research, and scales. According to Wimmer, a concept is "a term that expresses an abstract idea formed by generalizing from particulars and summarizing related observations" (Wimmer, 2011). He states that concepts are important because "they simplify the research process by combining particular characteristics, objects, or people into general categories and they simplify communication among those who have a shared understanding of them" (Wimmer, 2011). The idea behind measurement, according to Wimmer, is that "a researcher assigns numerals to objects, events, or properties according to certain rules" (Wimmer, 2011). A measurement contains numerals, assignments, and rules, where a numeral serves as a label, assignments are the designation of numerals to certain objects or events, and rules dictate the way numerals are assigned (Wimmer, 2011). There are four levels of measurement: nominal level, ordinal level, interval level, and ratio level. The nominal level, which is the weakest form of measurement, is when "numerals or other symbols are used to classify people, objects, or characteristics", for example, numbers on football jerseys.
