Consider the following statements regarding questionnaire preparation:

a. Questionnaires collect data by asking people to respond to different set of questions.

b. The validity and reliability of the data you collect and the response rate you achieve depend largely on the design of your questions.

C. Collect the data without a pilot test of all questionnaires.

d. When designing your questionnaire you should consider the wording of individual questions prior to the order in which they appear.

Which of the following statement is correct?

Statement a is INCORRECT: A fundamental characteristic of a questionnaire is that it collects data by asking each person to respond to the same set of questions (often in a predetermined order). Asking a "different set of questions" to different people defeats the purpose of standardized data collection.
