Questioning and Interview Schedule:

Meaning: The questioning is  a technique of data collection where  the sources  of data  is  the subject himself/herself.  Here, the data are collected through  self reporting which  requires some  form of  quest~oning  to  obtain needed information. Questioning  of subjects in a research project generally is accomplished through  the use  of a  formal instrument, which are: Interview  Schedule, Questionnaire or Opinionnaire. 

Interview schedule  is  an oral questionnaire.  Here  the researcher (interviewer) orally asks questions  to  the participant (interviewee) of  the study, either  in  face  to  face meeting  or  over the telephone  or video recording. Interviewing  is one of  the  questioning techniques  in which  the researcher  has  an ability  to control  the  level of questioning.  Interview Schedule  is a questionnaire (more structured) that is read to the respondents by  the  interviewer whereas  an  interview guide  (less structured) provides ideas but allows the  interviewer  a  freedom to pursue topics  in  depth. 

Questionnaire comprises  a series of  questions prepared  by  the researcher that are answered  and  filled in by all the respondents. This  is usually self- administered. The opinionnaire  is  a  type of questionnaire which  comprises  of a series  of questions  that may refer to matters of opinions to be  answered by  the respondents. The interview  schedule or  the questionnaire  the  researcher uses different  forms of questions,  such as  closed-ended  (or  fixed alternative),  open-ended or partially close-ended questions.
