 Sample screen shots

Screen shot
QDA Miner provides an intuitive environment for coding and annotating documents.
Screen Shot
QDA Miner also supports the coding of images, allowing codes to be applied to different elements of the image.
Screen Shot
QDA Miner provides many text search and coding retrieval tools.
Screen Shot
Presentation quality graphics such as pie charts and bar charts may be created to represent the frequency of codes.
Screen Shot
Bar charts may be plotted with the bars oriented vertically or horizontally
Screen Shot
Hierarchical clustering is a useful exploratory tool to quickly identify the co-occurrences of codes or the similarity of case (based on coding patterns).
Screen Shot
Multidimensional scaling maps may also be used to represent the proximity of codes or to find clusters of cases with similar coding patterns..
Screen Shot
This 3D multidimensional scaling can displays lines to represent how strongly related are data points.
Screen Shot
Proximity plots represent the distance of all codes to a specific one. It may also be used to represent the similarity of cases (based on the coding patterns).
Screen Shot
The Coding Sequences tool can be used to identify recurring sequences of codes.
Screen Shot
Bar charts may be used to represent the frequency of codes across values of a numerical or categorical variable.
Screen Shot
Bubble charts are graphic representations of contingency tables where relative frequencies are represented by circles of different diameters.
Screen Shot
Correspondence analysis is a powerful exploratory technique to identify relationships between codes and values of a numerical or categorical variable.
Screen Shot
Heatmaps are especially useful to explore large cross frequency tables and identify distribution patterns.
