概要	The discourse completion task (DCT) is an elicitation instrument widely used in pragmatics to gather data on how people perform speech acts such as requests, apologies, refusals, and compliments. Respondents read short descriptions of situations and write (or say) what they would utter in each, allowing researchers to collect comparable speech-act data across many speakers, languages, and cultures under controlled conditions. It was popularized by the Cross-Cultural Speech Act Realization Project (CCSARP) of Blum-Kulka, House, and Kasper in 1989.	Content analysis is a systematic research technique for reducing text, visual, or media material into coded categories so that patterns can be counted, compared, and interpreted. Formalised by Klaus Krippendorff in his widely cited methodology textbook (latest edition 2018), the method sits at the boundary of qualitative and quantitative inquiry: it imposes structured, replicable coding on inherently meaning-laden material.	Variationist sociolinguistics is the quantitative study of how linguistic variation is structured by social and linguistic factors. Pioneered by William Labov in the 1960s and 1970s, it treats alternative ways of saying the same thing — the 'linguistic variable' — as systematically conditioned by speaker characteristics (class, age, sex, ethnicity), stylistic context, and the surrounding linguistic environment, and it uses statistical modeling of natural speech to reveal the orderly heterogeneity beneath apparent randomness.
