Which of these is an example of an intervening variable? fear motivation gender age a and b none of the above18. What is the primary goal when writing survey questions? to word the questions so they have different meanings for all subjects to make them as unclear as possible to word the questions so they have the same meaning for all subjects a and b all of the above none of the above19. What is an advantage of open questions? responses can be coded, entered into a computer and analyzed responses are shallow easiest to analyze opportunity for respondent to give personalized answers20.
