Structured data analysis is the statistical data analysis of structured data. This can arise either in the form of an a priori structure such as multiple-choice questionnaires or in situations with the need to search for structure that fits the given data, either exactly or approximately.

This structure can then be used for making comparisons, predictions, manipulations etc. Find statistics, consumer survey results and industry studies from over 22, sources on over 60, topics on the internet's leading statistics database.
