Coding provides a way to manage your qualitative data—by creating nodes and coding at them, you can catalogue your ideas and gather material by topic.
Gather material from multiple sources into a node and explore the content in one place.
You can 'code on' from the references in a node—select the content and code it at the required nodes.
You can code the content of any source (whether imported or created in NVivo). The content available for coding includes:
Text—select and code text in documents, memos and externals. You can code as much text as required: a single letter, a few words, a whole passage or the entire source. The exact text you select and code is displayed in a node. You can choose whether you want NVivo to automatically code the whole word or just selected characters—refer to the General tab in Setting Application Options.
Tables in a document—click and drag to select and code text in a table.
Images in a document—click on an entire image to select and code it at the required node.
Pictures and log entries in a picture source—click and drag to select a region of a picture or text in the log and code it at the required node.
Video and audio—click and drag on the timeline to select and code the required portion of media.
Video and audio transcripts—click and drag text in the Content field and code it at the required node.
When you explore the source references gathered at a node, other themes or ideas may emerge. You can 'code on' by selecting and coding the content gathered in the node—this coding is reflected in the original source.
NVivo provides the following ways of coding your data:
Select the content in a source and use the Coding toolbar or Code menu to code at one or more nodes.
Use range coding to quickly code 'chunks' of text or other content.
Run a query and make a node from the results. For example, run a text search for the words friends and fun and automatically code them at a node called social interaction. In your sources, every occurrence of the search words will be automatically coded.
