สรุป	Rhetorical analysis, or rhetorical criticism, is the systematic interpretation of how symbolic messages — speeches, texts, images, campaigns — work to persuade audiences and create meaning. Rooted in classical rhetoric and codified for contemporary practice by scholars like Sonja Foss, it examines the strategies a message uses, the situation it responds to, and the effects it invites, producing an argued interpretation rather than a count.	Manifest content analysis is a quantitative research technique that systematically counts the explicit, surface-level features of communication messages — words, sources, themes, images, or actors that are directly visible in the text or media artifact — according to a predefined coding scheme. Rooted in Bernard Berelson's classic definition of content analysis as the 'objective, systematic, and quantitative description of the manifest content of communication,' it is one of the foundational empirical methods of mass communication and media research.
