Qualitative Data Collection Methods
Qualitative data collection methods are techniques used to gather non-numerical data such as words, experiences, perceptions, and behaviours in order to understand underlying meanings, motivations, and social contexts.

Qualitative vs quantitative methods
Qualitative research involves:
- Understanding why people behave in certain ways
- Exploring feelings, opinions, and experiences
- Analysing words, images, and interactions
It answers questions like:
“Why?”, “How?”, and “What does it mean?”
What are Qualitative Data Collection Methods?
Qualitative data collection methods are exploratory in nature and are mainly concerned with gaining insights and understanding on underlying reasons and motivations. Qualitative data is a linguistic or visual material. Qualitative data collection methods emerged after it became evident that traditional quantitative data collection methods were unable to express human feelings and emotions.
Monette et al (2010)[1] credit qualitative methods with the acknowledgement of abstraction and generalisation. Polonsky and Waller (2011)[2] categorize vision, images, forms and structures in various media, as well as, spoken and printed word and recorded sound into qualitative data collection methods.
Qualitative data collection methods are used in order to examine the following phenomenon:
- Human feelings and experiences
- Meanings and relationships
- Social norms and cultural practices.
It is noted that “qualitative methods are often regarded as providing rich data about real life people and situations and being more able to make sense of behaviour and to understand behaviour within its wider context. However, qualitative research is often criticised for lacking generalizability, being too reliant on the subjective interpretations by researchers and being incapable of replication by other researchers.”[3]
Types of Qualitative Data Collection Methods
Popular qualitative data collection methods used in business studies include interviews, focus groups, observation and action research. Moreover, grounded theory and document analysis can be also used as data collection method in qualitative studies. The main sources and procedures associated with the most popular qualitative methods are presented on Table 1 below as proposed by Yamagata-Lynch (2010)[4]:
| Methodology | Sources | Procedure |
| Document analysis | Reports, newsletters, publications | Read all materials and documented and descriptive statistics related to the research issue |
| Interviews | Primary participants
Secondary participants |
Tape recorded semi-structured interviews, then transcribed the interviews for the participants to review |
| Observations | Observed participants’ interactions | Took notes and videotaped the observations |
| Exit interviews
|
Primary participants
Secondary participants |
Presented findings to participants during individual or group interview sessions |
| Focus groups | Primary participants
Secondary participants |
Videotape focus group sessions

When to Use Qualitative Methods
Qualitative methods are most appropriate when your research aims to explore and understand complex phenomena.
You should use qualitative methods if:
- You want to understand motivations, perceptions, or experiences
- Your research is exploratory in nature
- The topic requires contextual and in-depth analysis
- You are studying social processes or behaviours
- You are following an inductive or interpretivist approach
