This study indicated that a variety of survey techniques resulted in a modest return rate (66%) in a national survey of 455 exercise professionals. A $1.00 bill incentive was significantly more effective than no incentive in improving returns, and the rate of double responses in this anonymous mail survey was extremely low (< 1%).
这项研究表明，在一项针对455名运动专业人士的全国性调查中，多种调查技术带来了适度的回复率（66%）。在提高回复率方面，一张1美元纸币的激励措施比无激励措施显著更有效，并且在这项匿名邮件调查中双重回复率极低（<1%）。
