The word qualitative implies an emphasis on the qualities of entities and on processes and meanings that are not experimentally examined or measured (if measured at all) in terms of quantity, amount, intensity, or frequency. Qualitative researchers stress the socially constructed nature of reality, the intimate relationship between the researcher and what is studied, and the situational constraints that shape inquiry. Such researchers emphasize the value-laden nature of inquiry. They seek answers to questions that stress how social experience is created and given meaning. In contrast, quantitative studies emphasize the measurement and analysis of causal relationships between variables, not processes. Proponents of such studies claim that their work is done from within a value-free framework. *
Qualitative forms of inquiry are considered by many social and behavioral scientists to be as much a perspective on how to approach investigating a research problem as it is a method.

The Design
Naturalistic--refers to studying real-world situations as they unfold naturally; non-manipulative and non-controlling; researcher is open to whatever emerges (there is a lack of predetermined constraints on findings).
Emergent--acceptance of adapting inquiry as understanding deepens and/or situations change; the researcher avoids rigid designs that eliminate responsiveness and pursues new paths of discovery as they emerge.
Purposeful--cases for study (e.g., people, organizations, communities, cultures, events, critical incidences) are selected because they are “information rich” and illuminative. That is, they offer useful manifestations of the phenomenon of interest; sampling is aimed at insight about the phenomenon, not empirical generalization from a sample to a population.
The Collection of Data
Data--observations that yield detailed, "thick description" (in-depth understanding); interviews that capture direct quotations about people’s personal perspectives and experiences; case studies; careful document review.
Personal experience and engagement--the researcher has direct contact with and gets close to the people, situation, and phenomenon under study; the researcher’s personal experiences and insights are an important part of the inquiry and critical to understanding the phenomenon.
Empathic neutrality--an empathic stance in working with study respondents seeks vicarious understanding without judgment (neutrality) by showing openness, sensitivity, respect, awareness, and responsiveness; in observation it means being fully present (mindfulness).
Dynamic systems--there is an attention to process; assumes change as ongoing, whether the focus is on an individual, an organization, a community, or an entire culture; therefore, mindful of and attentive to system and situation dynamics.
The Analysis
Unique case orientation--assumes that each case is special and unique; the first level of analysis is being true to, respecting, and capturing the details of the individual cases being studied; cross-case analysis follows from and depends on the quality of individual case studies.
Inductive analysis--immersion in the details and specifics of the data to discover important patterns, themes, and inter-relationships; begins by exploring, then confirming findings, guided by analytical principles rather than rules.
Holistic perspective--the whole phenomenon under study is understood as a complex system that is more than the sum of its parts; the focus is on complex interdependencies and system dynamics that cannot be reduced in any meaningful way to a few discrete variables and linear, cause and effect relationships.
Context sensitive--places findings in a social, historical, and temporal context; careful about, even dubious of, the possibility or meaningfulness of generalizations across time and space; emphasizes instead careful comparative case analysis and extrapolating patterns for possible transferability and adaptation in new settings.
Voice, perspective, and reflexivity--the qualitative methodologist owns and is reflective about her or his own voice and perspective; a credible voice conveys authenticity and trustworthiness; complete objectivity being impossible and pure subjectivity undermining credibility, the researcher's focus reflects a balance between understanding and depicting the world authentically in all its complexity and of being self-analytical, politically aware, and reflexive in consciousness.

Unlike positivist or experimental research that utilizes a linear and one-directional sequence of design steps, there is considerable variation in how a qualitative research study is organized. In general, qualitative researchers attempt to describe and interpret human behavior based primarily on the words of selected individuals (“informants” or “respondents”) and/or through the interpretation of their material culture or occupied space. There is a reflexive process underpinning every stage of a qualitative study to ensure that researcher biases, presuppositions, and interpretations are clearly evident thus ensuring that the reader is better able to interpret the overall validity of the research. According to Maxwell (2009), there are five, not necessarily ordered or sequential, components in qualitative research designs. How they are presented depends on the research philosophical and theoretical framework of the study, the methods chosen, and the assumptions underpinning the study.
Goals
Describe the central research problem being addressed but avoid describing any anticipated outcomes. Questions to ask yourself are: Why is your study worth doing? What issues do you want to clarify, and what practices and policies do you want it to influence? Why do you want to conduct this study, and why should we care about the results?
Conceptual Framework
Questions to ask yourself are: What do you think is going on with the issues, settings, or people you plan to study? What theories, beliefs, and prior research findings will guide or inform your research, and what literature, preliminary studies, and personal experiences will you draw on for understanding the people or issues you are studying? Note not just the results of other studies in your review of the literature, but the methods used as well. If appropriate, describe why earlier studies using quantitative methods were inadequate in addressing the research problem.
Research Questions
Usually there is a research problem that frames your qualitative study and influences your decision about what methods to use, but qualitative designs generally lack an accompanying hypothesis or set of assumptions because the findings are emergent and unpredictable. In this context, more specific research questions are generally the result of an interactive design process rather than the starting point for that process. Questions to ask yourself are: What, specifically, do you want to learn or understand by doing this study? What do you not know about the things you are studying that you want to learn? What questions will your research attempt to answer, and how are these questions related to one another?
Methods
Structured approaches to applying a method or methods to your study help to ensure that there is comparability of data across sources and researchers and, thus, they can be useful in answering questions that deal with differences between phenomena and the explanation for these differences (variance questions). An unstructured approach allows the researcher to focus on the particular phenomena studied. This facilitates an understanding of the processes that led to specific outcomes, trading generalizability and comparability for internal validity and contextual and evaluative understanding. Questions to ask yourself are: What will you actually do in conducting this study? What approaches and techniques will you use to collect and analyze your data, and how do these constitute an integrated strategy?
Validity
In contrast to quantitative studies where the goal is to design, in advance, “controls” such as formal comparisons, sampling strategies, or statistical manipulations to address anticipated and unanticipated threats to validity, qualitative researchers must attempt to rule out most threats to validity after the research has begun by relying on evidence collected during the research process itself in order to effectively argue that any alternative explanations for a phenomenon are implausible. Questions to ask yourself are: How might your results and conclusions be wrong? What are the plausible alternative interpretations and validity threats to these, and how will you deal with these? How can the data that you have, or that you could potentially collect, support or challenge your ideas about what’s going on? Why should we believe your results?
Conclusion
Although Maxwell does not mention a conclusion as one of the components of a qualitative research design, you should formally conclude your study. Briefly reiterate the goals of your study and the ways in which your research addressed them. Discuss the benefits of your study and how stakeholders can use your results. Also, note the limitations of your study and, if appropriate, place them in the context of areas in need of further research.

The advantage of using qualitative methods is that they generate rich, detailed data that leave the participants' perspectives intact and provide multiple contexts for understanding the phenomenon under study.
Among the specific strengths of using qualitative methods to study social science research problems is the ability to:
Obtain a more realistic view of the lived world that cannot be understood or experienced in numerical data and statistical analysis;
Provide the researcher with the perspective of the participants of the study through immersion in a culture or situation and as a result of direct interaction with them;
Allow the researcher to describe existing phenomena and current situations;
Develop flexible ways to perform data collection, subsequent analysis, and interpretation of collected information;
Yield results that can be helpful in pioneering new ways of understanding;
Provide a holistic view of the phenomena under investigation;
Interact with the research subjects in their own language and on their own terms; and,
Create a descriptive capability based on primary and unstructured data.

It is very much true that most of the limitations you find in using qualitative research techniques also reflect their inherent strengths. For example, small sample sizes help you investigate research problems in a comprehensive and in-depth manner. However, small sample sizes undermine opportunities to draw useful generalizations from or make broad recommendations based upon the findings. As the primary instrument of investigation, qualitative researchers are often imbedded in the cultures and experiences of others. This, however, increases the opportunity for bias to enter into the way data is gathered, interpreted, and reported.
Some specific limitations associated with using qualitative methods to study research problems in the social sciences include:
Drifting away from the original objectives of the research in response to the changing nature of the context;
Arriving at different conclusions based on the same information depending on the personal characteristics of the researcher;
An inability to investigate causality between different research phenomena;
Difficulty in explaining the difference in the quality and quantity of information obtained from different respondents and arriving at different, non-consistent conclusions;
Requires a high level of experience from the researcher to obtain the targeted information from the respondent;
May lack consistency and reliability because the researcher can employ different probing techniques and the respondent can choose to tell some particular stories and ignore others; and,
Generation of a significant amount of data that cannot be randomized into manageable parts for analysis.

Almost every socio-behavioral study requires you to submit your proposed research plan to an Institutional Review Board to evaluate and determine whether your research will be conducted ethically and under the regulations, institutional polices, and Code of Ethics set forth by the university. The purpose of the review is to protect the rights and welfare of individuals participating in your study. The review is intended to ensure equitable selection of respondents, that you have obtained adequate informed consent, there is clear assessment and minimization of risks to participants and to the university [read: no lawsuits!], and that privacy and confidentiality are maintained throughout the research process and beyond. Go to the UW-Superior IRB website for detailed information and templates of forms you need to submit before you can proceed. If you are unsure whether your study is subject to IRB review, consult with your professor or academic advisor.
