Any research method that produces unstructured data can be considered a qualitative research method. However, three types of qualitative methods are commonly used today to conduct data collection.

Observations

The simplest way to study a phenomenon is to look at it. Research conducted through direct observation involves collecting data in field notes, recordings of audio and video, and images for data analysis. This means that researchers can turn most forms of information into data that can be analyzed with qualitative methods. The illustrative examples qualitative research methods generate can help research audiences understand observed phenomena more clearly. ATLAS.ti can help with this process by allowing qualitative researchers to code major forms of data, including images and audio.

Interviews

Interviews are a fundamental method in qualitative research, allowing researchers to gather in-depth information about individuals' thoughts, feelings, experiences, and interpretations. Interviews can take various forms, from highly structured with predetermined questions, to semi-structured with some guidance, to unstructured or 'open-ended' where the conversation evolves based on the interviewee's responses. Conducting interviews offers a direct interaction with participants, enabling the researcher to probe deeper into the topics under discussion, clarify responses, and ask for elaborations. Interviews can yield rich, detailed data that provide a deep understanding of a person's perspective. However, they also require a significant investment of time and resources. Skilled interviewing and good rapport building are essential for collecting meaningful and accurate data.

Focus groups

A focus group consists of a group of participants collectively discussing a topic, speaking among themselves even more than they might speak to the researcher or focus group moderator. The aim is to inquire about people's perceptions, opinions, beliefs, and attitudes towards the topic of study, which could be a feature of social life, such as body art or a specific product, such as market research for a new campaign. Since the researcher can observe and speak with a group of people, focus groups are ideal for understanding the social construction of a phenomenon or how meaning is collectively co-constructed.

Focus groups are especially popular in market research. Still, qualitative researchers who want to observe how people interact with each other could consider conducting a focus group. For example, how people discuss their opinions and perspectives in groups is an essential inquiry in sociology and linguistics that focus groups can help explore.

Surveys

Surveys in qualitative research often differ from those in quantitative research, because an important part of these surveys is the collection of open-ended responses that allow participants to provide detailed responses in their own words. Surveys can be a cost-effective and efficient method to collect data from a larger number of participants compared to other qualitative methods. However, designing a good survey requires careful thought to ensure questions are clear, unbiased, and able to elicit rich, meaningful responses. Unlike interviews and focus groups, surveys do not provide an opportunity for the researcher to ask for clarifications or probe for more elaborate responses. Additionally, low response rates and self-selection bias can be potential challenges in survey research. Regardless, when designed and implemented effectively, surveys can provide valuable insights into participants' perspectives and experiences.

Document collection

Document collection is a versatile method in qualitative research that involves the analysis of existing texts. These texts can come in a variety of forms, such as official documents, newspapers, letters, diaries, transcripts, literary works, photographs, or even digital content like social media posts, blogs, and websites. The content of these documents can provide valuable insights into the phenomenon under investigation, contextual factors, and historical trends. The strength of document analysis lies in its ability to provide a behind-the-scenes look at events, settings, or groups, often complementing the data obtained through other methods. For example, it can be useful for triangulating data in a mixed-methods study or providing a historical context in a case study. However, the researcher needs to be cautious about the authenticity, bias, and representativeness of the documents. Despite these challenges, when used effectively, document collection can enrich a study by providing a diverse range of data and a deeper understanding of the research subject.

Other research methods

Ultimately, the potential for qualitative data collection is broad as it encompasses any research method that collects unstructured data that can be systematically organized and analyzed. With that in mind, let's briefly look at other methods that are useful in qualitative research. Participant observation - This is a method used frequently in ethnographic research. Researchers immerse themselves in the environment or culture they are studying, often participating in the activities of the group. This allows them to observe behaviors, interactions, and events as they naturally occur, leading to a deep understanding of the group's dynamics. Visual methods - These involve the use of visual materials, such as photographs, drawings, videos, or maps. Participants may be asked to create or interact with these materials as part of the data collection process. Visual methods can offer unique insights and are particularly useful when exploring topics that are difficult to express in words. Diaries and journals - In this method, participants are asked to keep a record of their experiences, thoughts, and feelings over a certain period. These records can provide rich, detailed, and longitudinal data. For example, diaries and journals are often used in health and social care research to study people's daily lives, experiences of illness, or caring roles. Life history - Collecting life histories is a type of narrative research where participants are asked to tell their life story or focus on a particular aspect or period of their life. Life history can reveal how people interpret and give meaning to their experiences over time.

How do I choose the best qualitative research method?

Think about what you want to study concerning a particular topic or concept. If your topic is education, for example, are you interested in what happens in education, what people think about it, or how people talk about it? Observations can tap into the experiences within a particular context, while interviews and focus groups can shed light on people's opinions. Also, keep in mind that the use of multiple qualitative research methods can provide a deeper exploration of a concept than the use of one method alone. A good research design for an in-depth qualitative study can even apply quantitative research methods in what is called mixed methods research to examine a phenomenon from different angles.
