Correspondence analysis is a technique for summarizing the data in a large table as a scatterplot, making it easier to identify the patterns. CorrespondenceTable1.PNG

To create a correspondence analysis map in Q:

  1. Create the table you want to analyze.
  2. Select Create > Dimension Reduction > Correspondence Analysis of a Table.
  3. Choose your table under Input table(s).
  4. 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:

Legacy Options

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.
