APPENDIX III: SURVEY RESPONSE REQUIREMENTS Required response rate for survey Equation 1. Response rate for projects with 500 or fewer occupants = 15% Response rate for projects with more than 500 occupants = 100 * (0.15/square root [occupancy/500]) Examples For a project with 200 occupants, the required response rate = 15% of 200. At least 30 survey responses are required. For a project with 800 occupants, the required response rate = 100 * (0.15/square root [800/500]) = 11.86% of 800. At least 95 survey responses are required.
附录III：调查回复要求 调查的必要回复率 公式1. 500人或以下使用者的项目回复率 = 15% 500人以上使用者的项目回复率 = 100 * (0.15/平方根[使用人数/500]) 示例 对于200人的项目，必要回复率 = 200的15%。至少需要30份调查回复。 对于800人的项目，必要回复率 = 100 * (0.15/平方根[800/500]) = 800的11.86%。至少需要95份调查回复。
