a. Direct and indirect questions – A direct question is undisguised whereas an indirect question is one that is disguised. Disguised questions are used when the interviewer and/or designer of the instrument does not wish the participants to know the research objectives and/or sponsors.

b. Open-ended and close ended questions – Open ended questions do not provide choices for the participant; close ended questions contain specific answers that the participant is required to ‘check-off.’

c. Research, investigative and measurement questions – Research questions are the “which option should we choose” type questions; they provide the choices available. Investigative questions are the questions that management should ask to be able to attain the information to make a choice. Measurement questions are the actual questions that will be asked of the participant.

d. Alternative response strategies – These are the various response types that can be provided to a candidate: Free Response; Dichotomous; Multiple Choice; Checklist; Rating and Ranking.
