What issues and problems might derive from the construction and administration of political surveys?

What will be an ideal response?

In order to obtain accurate, reliable, and affordable information, surveys must be administered to random samples of respondents. This requires a well-constructed (in both wording and question order) and error-minimized (through scientific sampling and sample selection procedures) instrument. But people often do not understand or are unable to effectively communicate their personal preferences and attitudes. This noninformation problem often leads to errors as well. Other problems with survey administration include sampling error, in which the sample drawn is not representative of the community as a whole, self-selection error (such as SLOP surveys), and interviewer error, in which questions are asked in a leading way or are not effectively communicated to the respondents. Other errors can take place in tabulating and interpreting the results. The degree of error must be calculated and transmitted to those who are interpreting the survey. For instance, a survey with ±3% degree of error is much more reliable than one with ±25% degree of error. Also, the aggregate degree of error may be misleading. Error and responses must be interpreted at the level of individual demographic variables such as age, gender, education, race/ethnicity, and political party affiliation.
