ICT
Interviews and observations
Provide you with data to back up or refute your theories and hypotheses.
Interview: Direct input collected from a specific person Used in obtrusive, respondent strategies.
Observation: Indirect input collected through observing a phenomenon in it
natural settings. Used in unobtrusive (ideally), field strategies
Both collect qualitative data. Structured interview might produce quantitative data as well.

Interview types
Structured Similar to questionnaire. Predefined questions, predefined answer alternatives.
Semi-structured Predefined topic and themes, open-ended questions.
Unstructured Predefined topic, open-ended themes and questions.
Semi-structured and Unstructured are more explorative, while Structured is more validating.

Researcher's role in interviews
Interviews are strongly vulnerable to bias on the side of the interviewer.
Interview design should take special care to eliminate bias: Who do you send to interview whom? Is the interviewer of the same or different social class, sex, ethnic
background etc. as the interviewee? How well-developed are the social skills of the interviewer?

ICT
Preparing for an interview
The basic rule is to treat your interviewee with respect and dignity! Do prior research on the interviewee's background. Schedule well ahead and don't plan for long interviews. Allow interviewee see the topic, themes and questions beforehand
and give feedback. Prepare for recording and ask prior permission. Pay attention to the seating arrangement during the interview. Start the interview with a clarification of goal, agenda, process. Make active use of prompts, probs and checks. Afterwards:
Do the transcribing and check the result with the interviewee before making public. Give "something" back to the interviewee as a thank you.

ICT
Group interviews
E.g. focus groups. Used frequently in new product design and evaluation. Has advantages and disadvantages compared to normal
interview: Can give better results because of the discussions among the
interviewees. Can give worse results because of the social hierarchies or other
issues among the interviewees.

Observation's goal
Find our what actually happens rather than what people think or say happens. Researcher uses all senses to collect field data.

ICT
Convert or overt?
Overt observations Agree with those being observed about the process.
Covert observations Researcher as a spy.
‘Hawthorn Effect ’ – people modify their behavior because they know they are being observed.

ICT
Systematic or participant?
Systematic observation: Pre-defined observation focus and plan (system of observation). Focus on e.g. "interactions among group members". Plan for what to observe, e.g. "number of times each member
talks" and "to whom each member talks". Often, researcher is an outsider.
Observation schedules, example:

ICT
Systematic or participant?
Participant observation: Researcher is a participant in the phenomenon being observed. No observation plan or schedule, open-ended notes. Often long-term. Overt or covert. Important to be clear about the "rules of the
game". The danger of "going native".
