概要	Q-sort is the data-collection technique at the heart of Q methodology, in which participants rank-order a set of statements or stimuli along a forced distribution (typically from 'most agree' to 'most disagree') to express their subjective point of view. In communication research it is used to uncover the shared patterns of opinion, framing, or media interpretation that exist within an audience, by factor-analyzing how people sort rather than how they score isolated items.	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.
