NIPO ODIN Version 5.17

Omnibus survey, using Sample tables and Omnibus tables

When using a Sample table rather than a telephone file for an omnibus survey, a sub-sample table must be created for every sub-survey in the questionnaire.The set-up is basically the same as when working with T-files, with some differences:

• The NIPO CATI / Web Master adds a new record in the Omnibus sub-sample table for each sub-questionnaire with a stratification file. This record contains the following information:
  
  InterviewNumber Questionnairename Success
  
• A field STData (varchar 12) will be available, when the following setting is written in the registry of the NIPO CATI / Web Master:
  
  STData:STData
  
  This field STData can be set in the sub-questionnaires by using the *COPY command on positions 2-12.
• *SAMPLEDATA in the first questionnaire of an Omnibus refers to database fields in the Sample table.
• *SAMPLEDATA in sub-questionnaires (all but the first) of the Omnibus refers to database fields in the Omnibus table.
• Stratification in sub-questionnaires can be based on fields in the Omnibus table or on fields in the Sample table. Use *SAMPLEDATA in the NIPO ODIN questionnaire or use the survey.INI settings RespondentFields and / or RespondentSubFields.
