Qualitative analysis of interview data: A step-by-step guide
The content applies to qualitative data analysis in general. Do not forget to share this Youtube link with your friends. The steps are also described in writing below (Click Show more): STEP 1, reading the transcripts 1.1. Browse through all transcripts, as a whole. 1.2. Make notes about your impressions. 1.3. Read the transcripts again, one by one. 1.4. Read very carefully, line by line. STEP 2, labeling relevant pieces 2.1. Label relevant words, phrases, sentences, or sections. 2.2. Labels can be about actions, activities, concepts, differences, opinions, processes, or whatever you think is relevant. 2.3. You might decide that something is relevant to code because: *it is repeated in several places; *the interviewee explicitly states that it is important; *you have read about something similar in reports, e.g. scientific articles; *it reminds you of a theory or a concept; *or for some other reason that you think is relevant. You can use preconceived theories and concepts, be open-minded, aim for a description of things that are superficial, or aim for a conceptualization of underlying patterns. It is all up to you. It is your study and your choice of methodology. You are the interpreter and these phenomena are highlighted because you consider them important. Just make sure that you tell your reader about your methodology, under the heading Method. Be unbiased, stay close to the data, i.e. the transcripts, and do not hesitate to code plenty of phenomena. You can have lots of codes, even hundreds. STEP 3, decide which codes are the most important, and create categories by bringing several codes together 3.1. Go through all the codes created in the previous step. Read them, with a pen in your hand. 3.2. You can create new codes by combining two or more codes. 3.3. You do not have to use all the codes that you created in the previous step. 3.4. In fact, many of these initial codes can now be dropped. 3.5. Keep the codes that you think are important and group them together in the way you want. 3.6. Create categories. (You can call them themes if you want.) 3.7. The categories do not have to be of the same type. They can be about objects, processes, differences, or whatever. 3.8. Be unbiased, creative and open-minded. 3.9. Your work now, compared to the previous steps, is on a more general, abstract level. You are conceptualizing your data. STEP 4, label categories and decide which are the most relevant and how they are connected to each other 4.1. Label the categories. Here are some examples: Adaptation (Category) Updating rulebook (sub-category) Changing schedule (sub-category) New routines (sub-category) Seeking information (Category) Talking to colleagues (sub-category) Reading journals (sub-category) Attending meetings (sub-category) Problem solving (Category) Locate and fix problems fast (sub-category) Quick alarm systems (sub-category) 4.2. Describe the connections between them. 4.3. The categories and the connections are the main result of your study. It is new knowledge about the world, from the perspective of the participants in your study. STEP 5, some options 5.1. Decide if there is a hierarchy among the categories. 5.2. Decide if one category is more important than the other. 5.3. Draw a figure to summarize your results. STEP 6, write up your results 6.1. Under the heading Results, describe the categories and how they are connected. Use a neutral voice, and do not interpret your results. 6.2. Under the heading Discussion, write out your interpretations and discuss your results. Interpret the results in light of, for example: *results from similar, previous studies published in relevant scientific journals; *theories or concepts from your field; *other relevant aspects. STEP 7 Ending remark Nb: it is also OK not to divide the data into segments. Narrative analysis of interview transcripts, for example, does not rely on the fragmentation of the interview data. (Narrative analysis is not discussed in this tutorial.) Further, I have assumed that your task is to make sense of a lot of unstructured data, i.e. that you have qualitative data in the form of interview transcripts. However, remember that most of the things I have said in this tutorial are basic, and also apply to qualitative analysis in general. You can use the steps described in this tutorial to analyze: *notes from participatory observations; *documents; *web pages; *or other types of qualitative data. STEP 8 Suggested reading Alan Bryman's book: 'Social Research Methods' published by Oxford University Press. Steinar Kvale's and Svend Brinkmann's book 'InterViews: Learning the Craft of Qualitative Research Interviewing' published by SAGE. Text and video (including audio) © Kent Löfgren, Sweden

Analysis of the data - How to write a research dissertation (ebook video)
http://www.etextbooks.ac.uk/dissertation/chapter-9-dissertation-analysis-of-the-data/ Once the research results have been carefully gathered and recorded using some filing system, the data needs to be able to be explained and interpreted in order to attempt to answer the initial research question. The type of analysis and the means of presentation need to be considered at an early stage – even before the results themselves have been obtained – in order to be certain that the research method(s) chosen can actually be used to generate sensible results. This chapter in the book outlines some key steps to ensure that your data analysis is appropriate for your needs. The companion website shares the experiences of some active researchers in how they approach data analysis in their own research areas.

What Is The Unit Of Analysis In Research? - Nerd-Out Wednesdays
The unit of analysis is the phenomenon or entity being studied. It is generally the thing that you are sampling in a quantitative study. It varies depending on what you are interested in. The unit of analysis may differ from the unit of observation, as you use the unit of analysis to explain the relationship set the theoretical level in the unit of observation occurs when you actually sample data. This idea of understanding the unit of observation versus the unit of analysis is important for quantitative research. The unit of analysis is important for both quantitative research and qualitative research, but it is often discussed in quantitative research. It differs from the level of analysis. The level of analysis generally pertains to the level at which you are analyzing a particular mechanism for a unit of analysis. For example, you might use population ecology to study the behavior of firms. Population ecology occurs at the population level (ie. aggregate) of firms but you are really studying firm behavior. It is important to get the right unit of analysis so that the theories you choose hold and are consistent when you analyze your data. For example, if you analyze transaction costs but then you look at firm behavior, you’re likely going to capture something other than transaction costs. Generally, you want to have the unit of analysis at the same level of analysis of your theory. You can also focus on a unit of analysis that cuts across levels of analysis. This is called multi-level theorizing, but it generally is not recommended because unless it is well done, it makes your paper seem very shallow. Most people end up just gathering theories from many different areas to explain the unit of analysis. The reason why you want to ensure that the unit of analysis in the level of analysis are similar is because you are unlikely to explain the phenomenon fully if you choose different levels of analysis, and rule out other possible explanations.

An integrated solution on Azure now extends, enhances, simplifies and accelerates the process.
Confirmatory Factor Analysis - Part 1 (Psychology, Statistics, Research Methods)
In intelligence research, personality research and other research fields of psychology, factor analytic models are used to structurize the variables' jungle. For example: To simplify the variable structure of a personality questionnaire several questions (items), that are supposed to measure the same construct are grouped to one (latent) factor (e.g. extraversion). But does this group of items really measure extraversion? Maybe some of the items "load" on a different factor. And Maybe other aspects of the model have flaws as well... How well a factor model fits the data can be examined by a confirmatory factor analysis. Keywords: Confirmatory Factor Analysis - Factor Analysis - Psychology - Statistics - Research Methods - Personality Psychology - Extraversion - Conscientiousness - Openness - Neuroticism - Agreeableness - Five Factor Model - Big Five - Intelligence - Carroll
