Abstract
Public Opinion Programme (POP) at the University of Hong Kong interviewed 1,008 Hong Kong people between November 2 and 6 by means of a random telephone survey conducted by real interviewers. Our latest survey shows that the support rating of CE Donald Tsang has further gone down by 1.2 marks to 52.7, close to the level registered before the Manila hostage incident two-and-a-half months ago. CE's net popularity now stands at negative 6 percentage points. For the Secretaries of Departments, compared to one month ago, the support ratings of CS Henry Tang and FS John Tsang have gone down by 1.7 and 1.1 marks respectively, while the support rating and approval rate of SJ Wong Yan-lung have remained stable. The net approval rates of the three Secretaries of Departments are Henry Tang positive 26, John Tsang positive 32 and Wong Yan-lung positive 53 percentage points respectively. Wong Yan-lung remains to be the most popular Secretary of Department. As for the Directors of Bureaux, compared to one month ago, the approval rates of 7 among 12 Directors have gone down, 4 have gone up and 1 remained unchanged. Among them, only Secretary for Food and Health York Chow has registered change in approval rates beyond sampling error, up by 6 percentage points, while those with changes in disapproval rates beyond sampling error include Secretary for the Environment Edward Yau, Secretary for Labour and Welfare Matthew Cheung, Secretary for Financial Services and the Treasury Ceajer Chan, Food and Health York Chow and Secretary for the Civil Service Denise Yue with disapproval rates up by 5, 4, 4 percentage points and down by 5 and 4 percentage points respectively. Among the Directors of Bureaux, those with negative popularity, meaning that disapproval rates higher than their approval rates, include Secretary for Home Affairs Tsang Tak-sing, Secretary for Education Michael Suen and Secretary for Constitutional and Mainland Affairs Stephen Lam. Their net popularity figures now stand at negative 4, negative 3 and negative 2 percentage points respectively. According to POP's standard, Ambrose Lee falls under the category of "ideal" performance. Wong Yan-lung, York Chow, Matthew Cheung and John Tsang now fall under the category of "successful". Carrie Lam, Henry Tang, Eva Cheng, Donald Tsang, Michael Suen, Edward Yau, Stephen Lam and Tsang Tak-sing can be labeled as "mediocre". Denise Yue, Ceajer Chan and Rita Lau can be labeled as "inconspicuous". No official falls under the category of "depressing" or "disastrous". The maximum sampling error of all approval and disapproval rates is between +/-2 and +/-4 percentage points at 95% confidence level, while the sampling error of rating figures needs another calculation. The response rate of the survey is 64%.
Points to note: [1] The address of the "HKU POP SITE" is http://hkupop.pori.hk, journalists can check out the details of the survey there. [2] The sample size of this survey is 1,008 successful interviews, not 1,008 x 64.1% response rate. In the past, many media made this mistake. [3] The maximum sampling error of all approval and disapproval rates is between +/-2 and +/-4 percentage points at 95% confidence level, while the sampling error of rating figures needs another calculation. "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. When quoting these figures, journalists can state "sampling error of various ratings not more than +/-1.3 and sampling error of percentages not more than +/-4% at 95% confidence level". [4] When quoting percentages of this survey, journalists should refrain from reporting decimal places, but when quoting the rating figures, one decimal place can be used, in order to match the precision level of the figures. [5] The data of this survey is collected by means of random telephone interviews conducted by real interviewers, not by any interactive voice system (IVS). If a research organization uses "computerized random telephone survey" to camouflage its IVS operation, it should be considered unprofessional. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Latest Figures
POP today releases on schedule via POP SITE the latest popularity figures of CE Donald Tsang, Secretaries of Departments and Directors of Bureaux 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-2010. 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 CE Donald Tsang are summarized as follows:
[9] These questions only use sub-samples of the survey concerned. The sub-sample sizes of questions on CE's support rating and hypothetical voting were 581 and 563 respectively. [10] Such changes have gone beyond the sampling errors at the 95% confidence level, meaning that they are statistically significant prima facie. However, whether numerical differences are statistically significant or not is not the same as whether they are practically useful or meaningful. Figures on the latest popularity ratings of the three Secretaries of Departments under the accountability system are summarized below:
[12] All error figures in the table are calculated at 95% confidence level. "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.
