After Preparing a Questionnaire but Before Submitting It to the Client

After preparing a questionnaire but before submitting it to the client for approval, the researcher should:

A) be aware of the number of attempts to contact respondents and complete a questionnaire.
B) work closely with data collection vendors to identify, target, and request participation from specific groups so accurate response rates can be calculated.
C) give the client an opportunity to provide suggestions of topics overlooked or to ask any questions.
D) obtain the final evaluation of the questionnaire from a pretest by asking respondents to pay attention to words, phrases, instructions, and question sequence.
E) review the document carefully to determine whether each question is necessary and if the overall length is acceptable.
