Qualitative analytical methods are essential tools in research that help us understand the complexities of human behavior, social phenomena, and cultural patterns. Unlike quantitative methods, which focus on numerical data, qualitative approaches delve into the 'how' and 'why' of a subject. One popular method is ethnography, which involves immersive observation and participation to gain insights into a community or culture. Another is in-depth interviews, offering a deep understanding of individual perspectives. Focus groups gather several participants to discuss a topic, providing a range of views and interactive dynamics. Content analysis allows researchers to interpret patterns in communication, such as themes in media or literature. Case studies provide an intensive examination of a single group, event, or individual, often over an extended period. Each method has its unique strengths, enabling researchers to construct a rich, nuanced picture of the subject at hand.
When selecting a qualitative method, researchers consider the nature of their research question and the depth of insight required. For instance, narrative analysis is excellent for exploring personal stories and experiences, revealing how individuals make sense of their lives. Grounded theory, on the other hand, is used to develop new theories based on data collection and iterative analysis. Discourse analysis examines how language is used in social contexts, uncovering the power dynamics and ideologies at play. Participant observation combines the observer's insights with the lived experiences of the subjects, often used in anthropological or sociological studies. While these methods lack the statistical power of quantitative analysis, they provide a rich, contextual understanding that numbers alone cannot convey, making them indispensable in many fields of study.
Qualitative analytical methods are diverse in their ability to analyze data and draw conclusions for non-numerical values. There are different types of qualitative analytical methods for different types of problems and data sets. For example, categorical data can be analyzed qualitatively based on patterns, themes or other relationships. Hierarchical data may warrant a qualitative approach based on the complexity of concepts, and may be further analyzed using a flow chart or diagram. The most common types of qualitative analytical methods are based on observation.
Qualitative research often is discussed in contrast with quantitative research. The difference between the two is based on the type of data and the method of analysis. If data are collected as numerical values, then a quantitative approach that often accompanies statistical analysis can be employed. On the other hand, qualitative techniques are intended for data sets that generally do not lend themselves to statistical analysis. Non-numerical data can be converted to numerical values using a ranking system or a series of codes.
Categories can be coded and the codes can be used for comparison. This do-it-yourself approach is technically referred to as the grounded theory method for comparative analysis. Barney Glaser and Anselm Strauss developed it in the 1960s. The “data” are organized based on four criteria: work, relevance, fit and modifiability. Qualitative analytical methods such as this can be used to analyze contextual data such as field or laboratory notes.
A visual representation of non-numerical data is another form of qualitative analysis. Flow charts, infographics and diagrams have the ability to take reasoning and an interpretation from data when it can be challenging to define relationships using another method from the list of qualitative analytical methods. A metaphorical method of analysis also can be used to understand the data set in terms of something more relatable. For example, analyzing chemical processes can be explained in terms of cooking, metaphorically speaking.
Most other types of qualitative analytical methods can be summarized under the umbrella of observation methods. Whether the observation involves animal behavior, semiotics or linguistics, the power of observation can easily be applied to many scenarios. Observations can be recorded in the form of notes, sketches or photographs. The “data” collected can be further analyzed using another qualitative analytical method to categorize or refine the observations. For example, frequency can be measured by counting the number of times a term is repeated in field notes.
