For example, the main questionnaire may consist of a household roster and other household information, and there may be a separate questionnaire for each woman in the household. Level: Level: – A level is a type of questionnaire – By default, all new dictionaries have one level – However, if you have ahierarchically-structured set of questionnaires, you will probably need to use additional levels – A level can have many records corresponding to different record types Author: Takdir, S.ST.

7 Record: Record: – A record usually corresponds to a section of a questionnaire – Consists of a group of related data items – If a dictionary contains more than one record, then you must use the record type item to identify one record from another in the data file Items: Items: – Contains the response to a question – Related items should be placed in the same record. Value Sets: Value Sets: – The responses in the questionnaire are defined as value sets – The valid values can be defined as individual values or ranges of values. Author: Takdir, S.ST.
