Additional notes

The Selected Variables tab has many of the same features as the Variable Search tab.

  • By default, the tab displays the list of tagged variables with RNUM, Question Name (QNAME), Variable Title, and Year.
  • Through the Settings menu, you can display additional variable characteristics, view data for a specific respondent, and navigate between respondents using the Show Data and Navigation Controls features described on the Customize Search Results page.
  • A variable's codebook information can be accessed through either the Codebook Preview or the Codebook tab.

Investigator limits extracts to 15,000 variables max

Research requiring more than 15,000 variables will need to divide variables into multiple tagsets for saving and downloading purposes.
