A variable is any concept that can take different values, such as age, media exposure, attitude, message framing, audience perception, or communication behavior. By identifying variables clearly, researchers are able to transform abstract communication concepts into measurable components, making systematic investigation possible. Variables help in explaining relationships between communication phenomena, predicting outcomes, and testing theoretical assumptions through empirical observation. In communication research, variables are commonly classified into independent, dependent, and control variables. The independent variable is the factor that is manipulated or considered as the cause influencing another variable. For example, in a study examining the impact of social media campaigns on public awareness, the type of campaign message can be treated as
