Correspondence analysis is a technique for summarizing the data in a large table as a scatterplot, making it easier to identify the patterns.
To create a correspondence analysis map in Q:
- Create the table you want to analyze.
- Select Create > Dimension Reduction > Correspondence Analysis of a Table.
- Choose your table under Input table(s).
- Click Calculate.
For more information on the options that are available, see Dimension Reduction - Correspondence Analysis of a Table.
Other related methods are also available from this part of the Create menu:
A webinar on using the correspondence analysis of a table is available here.
In older versions of Q, the option for creating a correspondence analysis was to use Create > Map (now available as Create > Dimension Reduction > Map). This option exports the correspondence analysis to Office. See Category:Maps for more detail.
