Queries & visualizations
Queries and visualizations support the iterative nature of qualitative research and can help you to investigate hunches as you progress through a project.
It is a good idea to start running queries early on—they can help you identify the questions you want to focus on (and prompt you to code accordingly). They can also help you to determine whether you need to gather additional data or re-frame the questions you are asking.
To start with, you may want to run some simple queries and preview the results. As you grow in confidence, you can look at building more complex criteria and storing your results in codes.
When you begin using queries it can help to remember:
- Coding queries rely on the work you have done— patchy or inconsistent coding may yield less useful results.
- Review the query results and make a memo to describe how it contributes to your understanding.
- While queries and visualizations can give you different perspectives on your data, you will still need to use your analytical skills to interpret the results.
- Saved queries can act as 'signposts' for future investigation, set them up early and rerun them as you progress through your project.
Query and visualize during your literature review
You can use NVivo for your literature review—and as your project progresses, you may return to the literature to see where your findings support or contradict those of other authors. As you conduct your literature review, you might use the following queries to explore the material:
Query and visualize during research design and data collection
In order to keep reliable records and enhance transparency, you can import your research design materials into NVivo—for example, you might import your thesis proposal, project-related timetables, or literature related to methodology.
During research design and data collection, you could create maps to:
- Show how you arrived at your approach to data collection and analysis
- Set out and review initial ideas, hunches or theories related to your research question
- Outline your project schedule, including dates and required tasks:
If you have imported literature related to research methods, you could run a Text Search query to find content based on keywords or use a Matrix Coding query to explore how different authors or researchers have applied a specific methodology.
As you move into the data collection phase of conducting interviews, surveys or focus groups you may want to collect demographic information about your respondents—for example, age, education level or location. You can import this 'classification' information or create it in NVivo—refer to Classify cases for information about how to do this. After classifying and setting up the attributes for your respondents, you can use queries or visualizations to explore your data. For example, you could:
- Create a chart to check the spread of your respondents—is a particular demographic under-represented? Do you need to collect data from a wider range of respondents?
Query and visualize during data analysis (coding)
Early on in your project, Text Search and Word Frequency queries can help you to organize your data into broad categories. For example, you could use a Text Search query to search for real estate development and automatically code all of the occurrences.
As you move into more detailed coding and continue to organize or 'segment' your data by theme—queries and visualizations can help you to reassemble and examine the themes in ways that address your research question. For example, you may want to explore the co-occurrence of themes (show me content coded to development AND water quality).
Rather than being a one-step process, querying your coding is iterative—one query or visualization may lead to another as you dig deeper into your data.
For example, to explore the idea that respondents are pessimistic about real estate development, you might run the following queries:
If you want to focus on the attitudes and experiences of a particular respondent—you might use the following queries and visualizations:
