Abstract

One of the main problems of survey methodology is related to possible biases due to the sampling method, especially biases related to low return rates. Currently, random telephone number generation is the most widely used methods in telephone surveys, which are still the most widely used sampling method in election polls. In recent years, Registration-based sampling (RBS) method has gain a lot of attention in public opinion research field and have been approved by many scholars for its effectiveness of gaining a
relatively representative sample. The present research focuses on two validation studies from the same community using RBS method.

The present research has two main purposes . First, the study tried to compare the survey response rates between telephone survey and mail survey under the condition of the same sampling method- RBS. Second, the current research also focused on the capacity of address-based sampling using voter registration lists to provide an accurate sample for election polls, both in telephone surveys and in mail surveys. This paper presents the results of two different studies completed in November 2008 and March
2009. The first used a telephone survey based on a sample drawn from a voter
registration list. The second used a mail survey based on a voter registration list as well.
