調查方法Back
| 所有行政會議非官方議員田北俊評分調查皆為電話問卷調查，由嚴格督導下的訪員進行訪問。 | |
| 訪問對像為十八歲或以上之操粵語的香港市民。 | |
| 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
 | All surveys on Rating of Non-Official Member of Executive Council James Tien Pei-chun are telephone surveys conducted by interviewers under close supervision. | |
| Target population of these surveys are Cantonese speakers in Hong Kong of age 18 or above. | |
| 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. |
