can be difficult to compare across cases have a single (numerical) answer

have a fixed number of predetermined choices (yes/no or strongly agree, agree, neutral, disagree, strongly disagree)

can easily be coded for computer analysis (e.g. from 1 to 5) Response Alternatives can heavily influence the response outcome Occupation of 18-25 year old Romanians People construe language in

What are your experiences about this job? You need to decide whether you want to ask leading or neutral questions Sampling Interviews Qualitative vs. Quantitative Survey Research Qualitative Quantitative tries to form a complete picture
explores a phonomenon, where it might not be clear to the researcher what exactly she is looking for – the focus becomes apparent through research
may yield descriptions of emotions or experiences
interprets findings, which most likely leads to some researcher bias is ideal to test hypotheses
the researcher needs to be clear about what it is that she wants to measure before collecting data
determines the size of an effect
analyses data through statistical methods Triangulation Facilitation Complementarity Cross-checking qualitative and quantitative data Qualitative research facilitates quantitative research
and vice versa Use qualitative and quantitative research side by side
to enrich each other Approaches to Qualitative Research Types of Interview Study Types of Interviews Analytic Techniques Case Study

Focus group

Ethnographic research

Grounded theory

... Positivist

Emotionalist

Constructionist Structured & standardised

Semi-structured

Unstructured, informal, narrative little flexibility, maybe miss out on something important explore a topic and move in any direction
dependance on what the participant talks about
good interpersonal skills needed systematic material, but informal tone Pattern matching

Explanation building

Time-series analysis

Cross-case analysis Population Sample Respondents Probability sampling Nonprobability sampling Every unit in the population has a chance of being selected Easily accessible individuals, e.g. people in a shopping mall in the morning Whereas systematic sampling techniques are more important in quantitative studies, accessibility and suitability of the research participants are more important issues in qualitative research
representative? A poorly constructed questionnaire will produce virtually useless results
Ethical Considerations Practical Considerations Nature of the research

Confidentiality

Anonymity Time management - being flexible Before During After Realistic interview partners

Different interests between researcher and company

Medium - In person, Telephone, ... Let the participant talk

Always ask for clarification if necessary

At the end, ask whether there is anything else worth considering Send participants a thank you note and feedback

Transcribe the interviews - 1 day per 1 hour interview remove anything that could lead to an identification of the person or the company Separate research question from survey questions Research question Hypotheses Constructs Survey questions
