Qualitative research is a broad field of inquiry that uses unstructured data collections methods, such as observations, interviews, surveys and documents, to find themes and meanings to inform our understanding of the world.^{[1] X Trustworthy Source PubMed Central Journal archive from the U.S. National Institutes of Health Go to source} Qualitative research tends to try to cover the reasons for behaviors, attitudes and motivations, instead of just the details of what, where and when. Qualitative research can be done across many disciplines, such as social sciences, healthcare and businesses, and it is a common feature of nearly every single workplace and educational environment.

Preparing Your Research

1
Decide on a question you want to study. A good research question needs to be clear, specific, and manageable. To do qualitative research, your question should explore reasons for why people do things or believe in something.^{[2] X Trustworthy Source PubMed Central Journal archive from the U.S. National Institutes of Health Go to source}
- The research questions is one of the most important pieces of your research design. It determines what you want to learn or understand and also helps to focus the study, since you can't investigate everything at once. Your research question will also shape how you conduct your study since different questions require different methods of inquiry.
- You should start with a burning question and then narrow it down more to make it manageable enough to be researched effectively. For example, "what is the meaning of teachers' work to teachers" is too broad for a single research endeavor, but if that's what you're interested you could narrow it by limiting the type of teacher or focusing on one level of education. For example, "what is the meaning of teachers' work to second career teachers?" or "what is the meaning of teachers' work to junior high teachers?"
Tip: Find the balance between a burning question and a researchable question. The former is something you really want to know about and is often quite broad. The latter is one that can be directly investigated using available research methods and tools.

A literature review is a process of studying what others have written about your research question and particular topic. You read widely on the larger field and examine studies that relate to your topic. You then draw up an analytical report that synthesizes and integrates the existing research (rather than simply presents a short summary of each study in chronological order. In other words, you are "researching the research."

For example, if your research question focuses on how second career teachers attribute meaning to their work, you would want to examine the literature on second career teaching - what motivates people to turn to teaching as a second career? How many teachers are in their second career? Where do most second career teachers work? Doing this reading and review of existing literature and research will help you refine your question and give you the base you need for your own research. It will also give you a sense of the variables that might impact your research (e.g., age, gender, class, etc.) and that you will need to take into consideration in your own study.

A literature review will also help you to determine whether you are really interested and committed to the topic and research question and that there is a gap in the existing research that you want to fill by conducting your own investigation.

Qualitative methods are useful when a question cannot be answered by a simple 'yes' or no' hypothesis. Often qualitative research is especially useful for answering "how" or "what" questions.^{[4] X Research source} They are also useful when budgetary decisions have to be taken into account.

For example, if your research question is "what is the meaning of teachers' work to second career teachers?", that is not a question that can be answered with a 'yes' or 'no'. Nor is there likely to be a single overarching answer. This means that qualitative research is the best route.

Qualitative research methods don't rely as heavily on large sample sizes as quantitative methods, but they can still yield important insights and findings.^{[5] X Trustworthy Source PubMed Central Journal archive from the U.S. National Institutes of Health Go to source} For instance, since it's unlikely that you have the funding to be able to study all second teachers everywhere in the United States, perhaps you choose to narrow your study to a major urban area (like New York) or schools within 200 kilometers (120 mi) of where you live.

Consider the possible outcomes. Because qualitative methodologies are generally quite broad, there is almost always the possibility that some useful data will come out of the research. This is different than in a quantitative experiment, where an unproven hypothesis can mean that a lot of time has been wasted.

Your research budget and available financial resources should also be considered. Qualitative research is often cheaper and easier to plan and execute. For example, it is usually easier and cost-saving to gather a small number of people for interviews than it is to purchase a computer program that can do statistical analysis and hire the appropriate statisticians.

The design of qualitative research is the most flexible of all the experimental techniques, so there are a number of accepted methodologies available to you.^{[6] X Trustworthy Source PubMed Central Journal archive from the U.S. National Institutes of Health Go to source}

Action Research – Action research focuses on solving an immediate problem or working with others to solve problem and address particular issues.^{[7] X Research source}

Ethnography – Ethnography is the study of human interaction in communities through direct participation and observation within the community you wish to study. Ethnographic research comes from the discipline of social and cultural anthropology but is now becoming more widely used.^{[8] X Research source}

Phenomenology – Phenomenology is the study of the subjective experiences of others. It researches the world through the eyes of another person by discovering how they interpret their experiences.^{[9] X Research source}

Grounded Theory – The purpose of grounded theory is to develop theory based on the data systematically collected and analyzed. It looks at specific information and derives theories and reasons for the phenomena.

Case Study Research – This method of qualitative study is an in-depth study of a specific individual or phenomena in its existing context.^{[10] X Research source}

Collecting and Analyzing Your Data

Each of the research methodologies has uses one or more techniques to collect empirical data, including interviews, participant observation, fieldwork, archival research, documentary materials, etc. The form of data collection will depend on the research methodology. For example, case study research usually relies on interviews and documentary materials, whereas ethnography research requires considerable fieldwork.^{[11] X Trustworthy Source PubMed Central Journal archive from the U.S. National Institutes of Health Go to source}

Direct observation – Direct observation of a situation or your research subjects can occur through video tape playback or through live observation. In direct observation, you are making specific observations of a situation without influencing or participating in any way.^{[12] X Research source} For example, perhaps you want to see how second career teachers go about their routines in and outside the classrooms and so you decide to observe them for a few days, being sure to get the requisite permission from the school, students and the teacher and taking careful notes along the way.

Participant observation – Participant observation is the immersion of the researcher in the community or situation being studied. This form of data collection tends to be more time consuming, as you need to participate fully in the community in order to know whether your observations are valid.^{[13] X Research source}

Interviews – Qualitative interviewing is basically the process of gathering data by asking people questions. Interviewing can be very flexible - they can be on-on-one, but can also take place over the phone or Internet or in small groups called "focus groups". There are also different types of interviews. Structured interviews use pre-set questions, whereas unstructured interviews are more free-flowing conversations where the interviewer can probe and explore topics as they come up. Interviews are particularly useful if you want to know how people feel or react to something. For example, it would be very useful to sit down with second career teachers in either a structured or unstructured interview to gain information about how they represent and discuss their teaching careers.

Surveys – Written questionnaires and open ended surveys about ideas, perceptions, and thoughts are other ways by which you can collect data for your qualitative research. For example, in your study of second career schoolteachers, perhaps you decide to do an anonymous survey of 100 teachers in the area because you're concerned that they may be less forthright in an interview situation than in a survey where their identity was anonymous.

"Document analysis" – This involves examining written, visual, and audio documents that exist without any involvement of or instigation by the researcher. There are lots of different kinds of documents, including "official" documents produced by institutions and personal documents, like letters, memoirs, diaries and, in the 21st century, social media accounts and online blogs. For example, if studying education, institutions like public schools produce many different kinds of documents, including reports, flyers, handbooks, websites, curricula, etc. Maybe you can also see if any second career teachers have an online meet group or blog. Document analysis can often be useful to use in conjunction with another method, like interviewing.

Once you have collected your data, you can begin to analyze it and come up with answers and theories to your research question. Although there are a number of ways to analyze your data, all modes of analysis in quantitative research are concerned with textual analysis, whether written or verbal.^{[14] X Trustworthy Source PubMed Central Journal archive from the U.S. National Institutes of Health Go to source}

Coding – In coding, you assign a word, phrase, or number to each category. Start out with a pre-set list of codes that you derived from your prior knowledge of the subject. For example, "financial issues" or "community involvement" might be two codes you think of after having done your literature review of second career teachers. You then go through all of your data in a systematic way and "code" ideas, concepts and themes as they fit categories. You will also develop another set of codes that emerge from reading and analyzing the data. For example, you may see while coding your interviews, that "divorce" comes up frequently. You can add a code for this. Coding helps you organize your data and identify patterns and commonalities.^{[15] X Research source tobaccoeval.ucdavis.edu/analysis-reporting/.../CodingQualitativeData.pdf}
Descriptive Statistics – You can analyze your data using statistics. Descriptive statistics help describe, show or summarize the data to highlight patterns. For example, if you had 100 principal evaluations of teachers, you might be interested in the overall performance of those students. Descriptive statistics allow you to do that. Keep in mind, however, that descriptive statistics cannot be used to make conclusions and confirm/disprove hypotheses.^{[16] X Research source}
Narrative analysis – Narrative analysis focuses on speech and content, such as grammar, word usage, metaphors, story themes, meanings of situations, the social, cultural and political context of the narrative.^{[17] X Research source}
Hermeneutic Analysis – Hermeneutic analysis focuses on the meaning of a written or oral text. Essentially, you are trying to make sense of the object of study and bring to light some sort of underlying coherence.^{[18] X Research source}
Content analysis/Semiotic analysis – Content or semiotic analysis looks at texts or series of texts and looks for themes and meanings by looking at frequencies of words. Put differently, you try to identify structures and patterned regularities in the verbal or written text and then make inferences on the basis of these regularities.^{[19] X Research source} For example, maybe you find the same words or phrases, like "second chance" or "make a difference," coming up in different interviews with second career teachers and decide to explore what this frequency might signify.
