Qualitative data
The term qualitative data or qualitative data material is understood to mean non-numerical material in empirical research ; corresponding methods have existed in social science since the 1990s. In contrast to numerical (quantitative) data, which are available in the form of numbers, non-numerical data are material that can be given or collected textually, verbally, visually or in a similar form .
Data material
As described above, qualitative (see Table 1 below) and quantitative ( number form ) data can be separated by their appearance. But there is no contradiction associated with this separation. On the contrary, a meaningful combination of qualitative and quantitative data and methods ( e.g. mixed methods approaches , triangulation , grounded theory, etc. ) can enrich research processes .
The following examples in Table 1 (see below) offer a more detailed overview of the forms of qualitative data material . The delimitation is to be understood as an example, since many data formats overlap.
shape | Present material | ||
---|---|---|---|
Textually | Newspaper articles | Diaries | Product logos |
Verbal | Audio recordings | Transcripts | Conversation protocols |
Medial | Chat rooms | Blogs | Websites |
Visually | film records | Photographs | Image sequences |
additional | drawings | SketchNotes | ... |
Data collection and data generation
Data collection and data generation must be separated because data can be collected on the one hand and generated on the other.
Furthermore, the separation describes a more broad and a narrow wider concept. The generation of data (more closely) refers to the active production of data - for example through an interview .
On the other hand, collecting data (more broadly) describes on the one hand the selection of existing data "from existing material" - for example a printed newspaper article - and on the other hand the expansion of the existing data through further production in the research process " - for example transcribing interviews.
The following table 2 (see below) provides a brief overview of qualitative methods for collecting data .
Survey procedure | description |
---|---|
Qualitative observation | Ethnographic field observations use open observation protocols or field notes as well as photos and video recordings that were created by the researchers. |
Qualitative interview | In the case of unstructured or semi-structured interviews, interview transcripts are produced in which the statements of the interviewees and respondents are contained verbatim. |
Qualitative questionnaire | In this process, free-text answers and essays are written by the study participants. |
Qualitative document analysis | Qualitative document analyzes use existing text, sound, image and video documents or other artifacts: e.g. B. newspaper articles, TV programs, contributions from online forums, house rules, letters, photo albums or children's drawings. |
Verbal data
From the perspective of a research culture, a difference can be made between the USA and Germany. In the USA, observation was the preferred method of data collection for a longer period of time. In Germany, on the other hand, the focus was on open interviews. Nonetheless, the focus has softened in recent years and other types of interviews (such as the guided interview) have come into focus. In summary, interviews, narratives and group procedures are central to generating and collecting data.
Interviews as an approach according to Flick
Interviews describe surveys that are carried out by questioners (called interviewers) with the aim of finding out personal or factual information from research participants.
One can hardly speak of "the" qualitative interview per se. The number and diversity of types and procedures is too wide and deep for that. In addition, even different specialist literature can come up with different terms for a form of interview.
Therefore - from a diverse number of qualitative interviews - the focused, semi-standardized, problem-centered and ethnographic interview is presented after the compilation by Flick (2016). The critical evaluation of the one-sided approach is left to the reader.
In addition to access to the interview, narratives and group procedures can also be used to generate and collect qualitative data (see Table 3).
Focused interview
The focused interview has been developed for the analysis of uniform media stimuli (film, radio broadcast, sound recording, etc.). A comparison between "objective" (facts) and "subjective" (interpretation) components should be possible through the uniform stimulus or incentive to talk and the subsequent interview.
To ensure the quality of the focused interview, the following components are provided:
- Not influencing the interviewees,
- Specificity of the point of view and definition of the situation from their point of view,
- Capture a wide range of the meaning of the stimulus and
- Profundity and personal frame of reference on the part of the respondents.
Semi-standardized interview
The semi-standardized interview can be used to reconstruct subjective theories . The concept of subjective theory describes the connection between freely expressible answers to open questions (explicit knowledge) and rather hidden perceptions (implicit assumptions) about an object of investigation. The subject in no way only means things, but also, for example, trust in relationships.
The structure of the answers is determined and their content validated at a second appointment via the survey using a guide. This procedure is known as validation using the structure-laying technique.
Problem-centered interview
The problem-centered interview is mostly used when biographical data relating to a specific problem are to be collected. Similar to the focused interview, there are certain components that characterize this format of the interview:
- Problem - a problem that is relevant to society or the person is focused by the researchers ,
- Subject - the data collection and data generation should develop and change based on the subject of interest,
- Process - the dialogue between people should enable the problem to be understood through more in-depth questions
The goal of the problem-centered interview is the "most unbiased recording of individual actions, subjective attitudes and ways of processing social reality.
Comparison of procedures for collecting verbal data
The survey methods can also be compared with one another in more detail. The following table 3 provides an overview of the possibilities and limits presented above for collecting qualitative data.

---|---|---|---|---|---|---|---|---|---|---|
Procedure ↦ | Focused | Semi-standardized | Problem centered | Experts | Ethnographic | Narrative | Episodic | Focus groups | Group discussion | Talking together |

Interviews as good practice
In order to produce usable qualitative data, good practice is required. The following are in 4 Table issues presented for reflection before the survey through interviews.
Checklist for choosing an interview type and evaluating its application | |
---|---|
1. Question |
• Can the interview type capture the essential aspects of the question?
• Can the application of the interview type capture the essential aspects of the question? |
2. Interview type |
• Is there a justification for jumping between interview types and stimuli in the question?
• Is jumping between interview types and stimuli in the theory part justified? |
3. Interviewer |
• Can interviewers use the interview type?
• What role do your own fears, insecurities and expectations play in the situation? |
4. Respondent |
• Is the interview type suitable for the target group of the application?
• How can fears, insecurities and expectations of interviewees be taken into account? |
5. Scope for respondents |
• Can the respondents present their point of view as part of the questions?
• Can the respondents assert their point of view against the framework of the questions? |
6. History of interaction |
• Did the interviewers realize the interview type? • Did the interviewers give the respondents enough leeway?
• Did interviewers cope with their role? Why yes or no? • Was their role clearly defined for the respondents? • Was the interviewer's role clearly defined for the respondents? • Was the situation clearly defined for the respondents? • Were the respondents able to match their roles? Why yes or no? |
7. Evaluation goal |
• Are narrowed-down answers the goal of the evaluation? • Are clear answers the goal of the evaluation?
• Are complex answers the goal of the evaluation? • Are complex patterns the goal of the evaluation? • Are contexts the goal of the evaluation? • What are the other goals of the evaluation? |
8. Claim to generalization | • At which level should statements be made? |
Generalization |
• About the individual case (e.g. about the interviewed person and their biography) • In relation to groups (e.g. about a professional group)
• Generally valid statements? |
Data interpretation
In addition to the collection of data, a distinction can also be made between the numerous analysis methods.
A subdivision and selection is made in Table 5 by distinguishing between specialized and general methods of data analysis.
