Final answer:
The statement regarding postal sampling frames having high response rates is false; such surveys typically have low response rates, leading to nonresponse bias and other issues. Researchers face challenges in ensuring data accuracy and representative samples across various polling methods, including internet surveys.
Step-by-step explanation:
The statement that one issue with postal sampling frames is the high response rates is False. In reality, postal surveys tend to suffer from low response rates, which can significantly impact the reliability and validity of the results. Additionally, such surveys face issues such as not knowing exactly who responded and the potential incompleteness of mailing lists.
These challenges associated with postal sampling frames have prompted many researchers to move towards internet-based methodologies, which come with their own set of problems. Ultimately, the trend in declining response rates is a global issue affecting not only postal surveys but also other methods like telephone and face-to-face polling, particularly in demographics such as younger and urban populations.
