調查方法
| 有關特首董建華評分的調查基本上每月進行兩次，但在回歸初期及一些重要月份（如特首發表施政報告的十月份）則會酌量增加。這個模式在九二年彭定康成為末任港督時已經確立。 | ||
| 所有調查都是在嚴格督導下由訪員親身進行電話訪問，對象皆為十八歲或以上之操粵語的香港市民。 | ||
| 各次調查的成功樣本數目都在五百以上。二千年五月份起，成功樣本數目更增加至一千以上，兼且根據香港人口的年齡性別分佈加權調整。 | ||
| 電話號碼抽樣方法是從住宅電話簿中首先以隨機方法抽取「種籽」號碼，再以加一減一加二減二的方法產生另一組號碼，然後在混合後再過濾重覆號碼，再以隨機排列方式排次成為最後樣本。 | ||
| 抽取住戶成員的方法是由訪員在成功接觸目標住戶後，用「即將出生日期」的方法由當時在家的成員抽取其中一人進行訪問。 | ||
Survey Method
 |
Surveys on the rating of the SAR Chief Executive Tung Chee-hwa are basically conducted twice every month. It was more conducted more frequently immediately after the handover and in special months (such as in October when the CE delivers his policy addresses). This has been the case since 1992 when Chris Patten became the last Governor of Hong Kong. | ||
|
All these surveys are conducted by telephone interviewers under close supervision. Target population of these surveys are Cantonese speakers in Hong Kong of age 18 or above. | ||
|
The sample size of all these surveys are more than 500 successful cases each time. Since May 2000, it has been increased to more than 1000, and weighted according to gender-age distribution of the Hong Kong population. | ||
|
Telephone numbers are first selected randomly from telephone directories as seed numbers. Another set of numbers is then generated by using the plus/minus one/two method. Duplicate numbers are then screened out, and the remaining numbers mixed in a random order to become the final sample. | ||
|
Upon successful contact being made with a target household, one member of the household is selected among those present using the "next birthday" rule. | ||
