Introduction to QDA

QDA is a process of applying thematic codes to documents or segments within them, to aid in analysis. For example, individual responses within a series of interview transcripts could be annotated with thematic codes such as “wholesale price”, “well-being”, “labour”, “role of children”, and the like, matching the content of each response. The QDA software application can then aggregate all passages matching the same theme, providing a simple way of looking for commonalities and variations across a large dataset.
