Observational Analysis: Researchers observe and record conversations to study how individuals from diverse linguistic backgrounds interact.
Transcription: Spoken language is transcribed into written form for detailed analysis, including pronunciation, intonation, and pauses.
Coding and Categorization: Linguistic patterns and sociolinguistic variables are identified in transcripts, such as code-switching and language choices.
Quantitative Analysis: Statistical techniques may quantify sociolinguistic phenomena like code-switching frequency or linguistic feature distribution.
Qualitative Analysis: Researchers explore the meaning and context behind linguistic behaviors and language choices.
Questionnaires and Surveys: Self-reported data from participants, including language preferences and attitudes toward languages, can be collected.
Corpus Linguistics: Large collections of texts or spoken data are analyzed to uncover linguistic patterns.
Experimental Studies: Researchers design experiments to manipulate variables related to peer interactions and sociolinguistic competence.
Interviews: Semi-structured interviews provide insights into participants' experiences and perceptions.
Audio and Video Recordings: Recordings capture spoken and nonverbal aspects of communication, such as gestures and facial expressions.
I would add conversation analysis, such as discourse markers, prefaces, tails, ellipsis, etc. (I don't know if this falls in your category of "transcription"). Also, I would include the annotation of non-words, such as filled pauses ("er"), response tokens ("uh uh"), tokens marking hesitation or a thinking attitude ("mmm") and so on.
Thank you for the answer. I think that would also help. I wasn't thinking of discourse markers, however they are very important for conversation analysis.
Thank you for your reply, Zafar. I mean, coud you let me see what kind of questionnaires you are designing? For example, did you use Likert scale or other scales? From what kind of people would you like to get replies or data based on your questionnaire?@Zafar
Firstly, Try Finding out if the speakers are Bilinguals or multilinguals and approach from Language varieties based on social groups or Peer groups because most times, a speaker’s multilingual environment but bilingual nature which may differ from their peers may affect sociolinguistic competence. Secondly, I recommend using observation or interviews where you target accessing information from the Ethnographic angle.
