抄録

The Mainichi Shimbun conducted a Telephone Survey before the 19th Upper House Election of Japan in July, 2001. In that Survey, a kind of media poll, two types of Telephone Survey Method were used, the Telephone Directory Method (the TD Method), and the Random Digit Sampling Method (the RDS Method). The TD Method was used to cover 32 electoral districts in rural areas and the RDS Method was employed for 15 districts in mega-city areas. When compared with the ballots of candidates of all districts in the Upper House Election, the polls of these two types of Telephone Survey Method and the regression analysis based on the polls had effectively corresponded to the results of the Japanese voters' choices. Nevertheless, considering that the precision of a survey depends on rigid examination, which involves the representativeness of the sample, valid response rates, and the characteristics of respondents, the TD Method has a vital problem impossible to eradicate, and the RDS Method has quite a few faults to correct, as well.
