Types and Structure:

Types and Structure The  design of a useful  schedule normally  involved extensive planning, consultation with  colleagues and experts, pretesting and revising.  Some of the major considerations that to be kept in mind when  constructing a questionnaire andlor  interview  schedule are: 

i) Form of Schedule Schedules vary  in extent  to which  they  are  structured. These can be  structured, seini-structured,  unstructured. Majority of  the interview  schedule and questionnaire fall  in between these  two  extremes of rigid standardization (structured) and total absence of  structure (unstructured).  That  is, schedules  are most  often  composed  of a combination  of questions which vary in  their degree of  structure. In general, questionnaire tend to  be more standardized than interview schedule.

ii) Form of Question Review the  forms of question which could  be  close-ended, open-ended and partially close-ended questions. Some  advantages and disadvantages of open and close-ended question are listed in Fig. The partially close-ended questions provide a compromise. Although answer choices are provided, respondents have option of  creating their own responses also.
