When Paul Erdos started Erdos & Morgan in 1946, the best way to get usable information was the direct mail survey. Dr. Erdos devoted much of his career to understanding how to:
- Design effective mail survey instruments
- Reach and recruit the right audiences
- Ensure statistically significant response rates
Dr. Erdos took copious notes and eventually compiled everything he had learned into a book, Professional Mail Surveys, originally published in 1970, revised in 1983 and reissued in 1990. This book is still the definitive guidebook on the subject. We would be delighted to provide you with a complimentary copy. Simply fill out the form located on the Contact page.
