調查方法 Survey Method返回


調查方法

 

 有關特區第四屆立法會議員整體表現的調查皆是由嚴格督導下由訪員親身進行的電話問卷訪問。
 

  調查自二零零八年十二月起(即第四屆立法會議員上任起)每三個月起碼進行一次。
 

  所有調查的訪問對象皆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 the overall performance of members of the Fourth HKSAR Legislative Council are conducted by telephone interviewers under close supervision.

 
 

Such surveys began in December 2008 (when the session of the Fourth HKSAR Legislative Council began) and are conducted at least once every three month.

 
 

Target population of these surveys are Cantonese speakers in Hong Kong of age 18 or above.

 
 

Starting from mid-January 2014, telephone numbers are randomly generated using known prefixes assigned to telecommunication services providers under the Numbering Plan provided by the Office of the Communications Authority (OFCA). Invalid numbers are then eliminated according to computer and manual dialing records to produce the final sample.

 
 

Before mid-January 2014, 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.
