About WordStat: WordStat is a content analysis and text mining module specifically designed to analyze textual information such as responses to open-ended questions, interviews, titles, journal articles, public speeches, electronic communications, etc. It provides numerous statistical and graphical tools to visualize text and examine the
relationship between words or categories of words and the values of categorical and numerical variables (cluster analysis, multidimensional scaling, proximity plot, correspondence plot, heatmap, bar chart, line chart, crosstabulation, statistical
association measures, etc.). Such tools allow users to compare how different groups differs in vocabulary usage, discussed topic, or content category. They also may be used to uncover existing relationships between specific categories of words and numeric
variables such as age of the respondent, year of publication, etc. WordStat can analyze text directly or apply categorization dictionaries to group words with similar meanings. The program also provides numerous tools to facilitate the development and validation
of new categorization dictionaries.
