Assignment:
Political scientists who are interested in survey research often must deal with tough issues of validity. A survey question may not be valid, because it does not tap the intended characteristic. Sometimes, too, a survey question may gauge an unintended characteristic.
Below are three hypothetical survey questions.
For each one: (i) Describe why the question is not a valid measure of the intended characteristic. (ii) Rewrite the survey question to improve its validity.
Example. Intended characteristic: Whether or not an individual voted in the 2012 election.
Survey question: "Thinking about the 2012 election, some people did their patriotic duty and voted in the election. Others were too unpatriotic to vote. How about you-did you vote in the 2012 election?"
(i) This question is not valid because it also measures individuals' feelings of patriotism. Not wanting to appear unpatriotic, citizens who did not vote may respond that they did vote.
(ii) Improved rewrite: "Thinking about the 2012 election, some people voted in the election, whereas other people did not vote. How about you-did you vote in the 2012 election?"
A. Intended characteristic: Respondents' position on the trade-off between protecting the environment and creating jobs. Survey question: "Which of the following comes closest to your opinion about the trade-off between protecting the environment and creating jobs:
'We should regulate business to protect the environment and create jobs.' OR 'We should not regulate business because it will not work and will cost jobs'."
B. Intended characteristic: Attitudes toward Social Security reform. Survey question: "Some politicians, mostly Republicans, have proposed that the Social Security system be replaced by a system that allows people to invest in the stock market. Other politicians, mostly Democrats, oppose the Republican plan. Would you support or oppose replacing the Social Security system with a system that allows people to invest in the stock market?"
C. Intended characteristic: Attitudes toward dealing with crime. Survey question: "Some people think that the way to solve crime is to have harsher punishment for criminals.
Others think that the way to solve crime is to improve our educational system. What do you think-should we have harsher punishment for criminals or should we improve our educational system?"
