HKU POP SITE releases the latest popularity figures of CE Donald Tsang and Principal OfficialsBack

Since January 2007, the Public Opinion Programme (POP) at the University of Hong Kong has launched a feature page called "Opinion Daily" at the "HKU POP SITE" (http://hkupop.pori.hk). It records significant events on a daily basis, as well as provides certain opinion poll figures on those separate days. Our purpose is to provide accurate information for readers to judge by themselves the reasons for the ups and downs of opinion figures. "Opinion Daily" began to operate on January 17, 2007. At the beginning, it only recorded significant events and the popularity figures of the Chief Executive for the previous few months. As of today, it gives a chronology of events back from May 1, 2006, and many other poll figures since January 1, 2006, and its content is ever increasing.

In July 2007, POP collaborated with Wisers Information Limited whereby Wisers supplies to POP since July 24 on a daily basis a record of significant events of the day, according to a research method designed by POP. These daily entries would be uploaded to the "Opinion Daily" feature page as soon as they are verified by POP, in order to provide readers with swifter and more accurate information.

Starting today, other than reading the chronology of significant events, readers can also check on the results of 9 different polling items compiled by POP, including the popularity of the Chief Executive, the HKSAR government, and the Secretaries of Departments under the accountability system. In near future, "Opinion Daily" will be regularly updated and expanded in order to promote the science of opinion polling.

Besides, since mid-August 2007, in POP's regular press releases, we have listed some of the more significant events which happened in between two surveys for readers to make their own judgment whether these events have any effect on polling figure changes.

POP today releases on schedule via the POP Site the latest figures of CE Donald Tsang and Principal Officials under the accountability system. All the figures have been weighted according to provisional figures obtained from the Census and Statistics Department regarding the gender-age distribution of the Hong Kong population in mid-2007. Herewith the contact information for the latest survey:

As different questions involve different sub-samples, the sample errors will vary accordingly. The table below briefly shows the relationship between sample size and maximum sampling errors for the readers to capture the corresponding changes:

"Maximum sampling errors" occur when survey figures are close to 50%. If the figures are close to 0% or 100%, the sampling error will diminish accordingly. The sampling errors of ratings, however, will depend on the distribution of the raw figures. Since January 2007, POP lists out the sampling errors of all survey figures in detail and explain them in due course. Recent popularity figures of Donald Tsang are summarized as follows:

* "95% confidence level" means that if we were to repeat a certain survey 100 times, using the same questions each time but with different random samples, we would expect 95 times getting a figure within the error margins specified. Media can state "sampling error of ratings +/-1.2, sampling error of percentages not more than +/-3% at 95% confidence level" when quoting the above figures.

Figures on the latest popularity ratings of the three Secretaries of Departments under the accountability system are summarized below:

* The frequency of this series of questions is different for different questions, and also different from that of CE popularity ratings. Comparisons, if made, should be synchronized using the same intervals.
** "95% confidence level" means that if we were to repeat a certain survey 100 times, using the same questions each time but with different random samples, we would expect 95 times getting a figure within the error margins specified. Media can state "sampling error of various ratings not more than +/-1.2, sampling error of percentages not more than +/-3% at 95% confidence level" when quoting the above figures.
^ Henry Tang has been appointed as CS from 1 July 2007 onwards. Prior to that he was the FS.

Figures on the latest popularity ratings of Directors of Bureaux under the accountability system are summarized below: 

* Starting from 2006, these questions only uses sub-samples of the tracking surveys concerned, the sample size for each question also varies.
** "95% confidence level" means that if we were to repeat a certain survey 100 times, using the same questions each time but with different random samples, we would expect 95 times getting a figure within the error margins specified. Media can state "sampling error of percentages not more than +/-4% at 95% confidence level" when quoting the above figures.
# This series of questions is conducted once every month since July 2007, different from the frequency of support ratings. Comparisons, if made, should be synchronized using the same cycle.

In between these two surveys, herewith the significant events selected from counting newspaper headlines and commentaries on a daily basis and covered by at least 25% of the local newspaper articles. Readers can make their own judgment if these significant events have any impacts to different polling figures.

Commentary

Robert Ting-Yiu Chung, Director of Public Opinion Programme, observed, "Our latest survey shows that compared to two weeks ago, the support rating of CE Donald Tsang has dropped while his support rate has gone back to the 'ideal' level. Since POP has already proposed a set of benchmarks for measuring the popularity of principal officials quite some time ago, we have specially added a summary table on the ranking of principal officials to this release for readers' easy reference. According to the table, the performance of Ambrose Lee, Wong Yan-lung and Donald Tsang can be labeled as 'ideal', that of Henry Tang and York Chow can be labeled as 'successful', that of Carrie Lam, Matthew Cheung, Frederick Ma, Michael Suen and Stephen Lam can be labeled as 'mediocre', and that of Denise Yue, John Tsang, Ceajer Chan, Tsang Tak-sing*, Eva Cheng and Edward Yau can be labeled as 'inconspicuous'. No official falls under the categories of 'depressing' or 'disastrous'. As for the reasons affecting the popularity change of these officials, readers can make their own judgment according to our records shown in our 'Opinion Daily' feature page."

Regarding the grading system of these officials, Robert Chung further explained, "A new grading system was adopted for 2007 HKCEE Chinese Language and English Language, whereby the old 'pulling curve' system using a six-grade norm reference approach was replaced by a standard-referenced approach with six grades from Level '1' to '5*'. This should have deepened people's understanding of the standard-referenced approach, which is fairly similar to POP's grading system of principal officials. We therefore would not object to community members using Level '1' to '5*' to describe the popularity of principle officials."

* Tsang Tak-sing was placed accidentally before Ceajer Chan in the original draft of the commentary.

In the near future, we will keep on stepping up our effort in promoting general civic education to enhance our POP Site accordingly

About HKUPOP

Popularity surveys of CE and principal officials

In advanced democratic countries, the popularity of top leaders and principal officials is the crux of all opinion polls. Shortly after HKUPOP was established, we started to conduct surveys on these aspects. We have explained the development of these surveys in our press releases of October 31, 2006, January 16 and 31, February 8, March 13, June 12, July 17 as well as August 14, 2007. Today, we post it again, so that readers can have a more comprehensive picture of such development. 

(1) Development of CE's popularity survey

• From its establishment to the handover of Hong Kong, POP has continually conducted surveys to measure the popularity rating of Governor Chris Patten. After the handover when Tung Chee-hwa became the first Chief Executive in 1997, we began our popularity survey of CE Tung Chee-hwa. After Tung resigned and Donald Tsang succeeded, POP has begun to measure Tsang's popularity. The frequency of our surveys was at least once every month during the Patten era. It was then increased to three times per month when Tung became CE, until the end of 1997. From January 1998 onwards, it was reduced to twice every month.
  
  

• The question wordings used in "popularity of Governor or CE" survey are: "Please use a scale of 0-100 to rate your extent of support to the Governor/ the Chief Executive XXX, with 0 indicating absolutely not supportive, 100 indicating absolutely supportive and 50 indicating half-half. How would you rate the Chief Executive XXX?" and "If a general election of the Chief Executive were to be held tomorrow, and you had the right to vote, would you vote for XXX?".
  
  

• Before April 2000, the sample size of our regular surveys was set at slightly over 500. After that, it was increased to at least 1,000.

(2) Development of CE's popularity (performance) survey

• The frequency of our surveys was once every two months since August 2002. From February 2004 onwards, it was reduced to once every six months.
  
  

• The question wordings used in "CE popularity (performance)" survey are: "Do you think XXX is doing a good or bad job as CE?".
  
  

• Regarding the sample size, ever since the beginning, the sample size of surveys has been set at slightly over 1,000.

(3) Development of the survey for Secretaries of Departments:

• For the rating survey of the Secretaries of Departments, in between January to November 2001, the survey was conducted at an irregular basis. From January 2002 onwards, the survey is conducted once every month. For the support rates of the Secretaries based on people's hypothetical vote of confidence, it was surveyed once every three months from September 2002 to December 2003. Then it was changed to once every two months from February 2004 to December 2005. From January 2006 onwards, the survey is conducted once every month.
  
  

• The wordings used in the questionnaire are: "Please use a scale of 0-100 to rate your extent of support to Chief Secretary for Administration XXX/Financial Secretary YYY/Secretary for Justice ZZZ, with 0 indicating absolutely not supportive, 100 indicating supportive and 50 indicating half-half. How would you rate XXX/YYY/ZZZ?". For the support rates of Secretaries, the wordings are "If you had the right to vote on the reappointment or dismissal of XXX/YYY/ZZZ as the Chief Secretary for Administration/Financial Secretary/Secretary for Justice tomorrow, how would you vote?"
  
  

• Regarding the sample size, ever since the beginning, the sample size of surveys has been set at slightly over 1,000. 

(4) Development of the survey for Directors of Bureaux:

• For the rating survey of the Directors of Bureaux, in between June 2002 to December 2005, the frequency was once every month. From January 2006 to June 2007, the survey is conducted once every two months. For the support rates of Directors of Bureaux, the frequency was once every three months from September 2002 to December 2003. Then from February 2004 to June 2007, the survey was conducted once every two months. In July 2007, with the beginning of CE's new term of office and the appointment of new principal officials, the frequency of support rate survey of the Directors of Bureaux was increased to once every month, while the frequency of rating survey was reduced to once every three months. Moreover, although all survey results are uploaded onto the POP Site in detail, POP no longer analyze the result of rating surveys. This is to better match the evolvement of the accountability system as well as the pace of democratic development.
  
  

• Similar to the popularity survey of the Secretaries of Departments, that of the Directors of Bureaux also includes the questions of rating and hypothetical voting. The wordings used in the questionnaire are: "Please use a scale of 0-100 to rate your extent of support to XXX, with 0 indicating absolutely not supportive, 100 indicating supportive and 50 indicating half-half. How would you rate XXX?" and "If you had the right to vote on the reappointment or dismissal of XXX as YYYYYY tomorrow, how would you vote?" However, the two questions may not be asked in the same survey.
  
  

• Regarding the sample size, from the beginning to December 2005, the sample size of the surveys was set at slightly over 1,000. However, from 2006 onwards, this series of questions only uses sub-samples of the tracking surveys concerned, and the sample size for each question also varies.

All the findings from our surveys on "popularity of principal officials" have been released online through our HKU POP Site.
