Consider Creating an "Answer Sheet"

If your questionnaire format does not make answers obvious, develop an "answer sheet" separately or right on the questionnaire that provides the replies that qualify a participant and how many of each category you need.
This can be as simple as a table or spreadsheet. We like a spreadsheet such as the one in Figure 7-5 better because you can later filter and sort the data you have gathered. (For an expanded sample of such a spreadsheet, go to the web site that accompanies this book: ww.wiley.com/usabilicytescing.com.)
