Abstract POP interviewed 1,010 Hong Kong people between October 6 and 11 by means of a random telephone survey conducted by real interviewers. The survey shows that compared to two weeks ago, CE Donald Tsang's support rating and approval rate remain unchanged. His net popularity still stands at positive 7 percentage points. For the Secretaries of Departments, compared to one month ago, the support ratings and approval rates of CS Henry Tang, FS John Tsang and SJ Wong Yan-lung have all gone up significantly, especially for John Tsang whose approval rate surges 17 percentage points. This shows that 「a little illness may be a good thing」. The net approval rates of the three officials now stand at positive 42, 47 and 59 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 most Directors have remained unchanged. Those with changes beyond sampling error include only Secretary for Development Carrie Lam, with approval rate up 5 percentage points, and Secretary for Commerce and Economic Development Rita Lau, with approval rate down 5 percentage points. Among the Directors of Bureaux, Secretary for Education Michael Suen, Secretary for Constitutional and Mainland Affairs Stephen Lam and Secretary for Home Affairs Tsang Tak-sing register negative popularity, meaning that their disapproval rates are higher than their approval rates. Their net popularity figures now stand at negative 3, negative 3 and negative 1 percentage point. According to the benchmarks set by us quite some time ago, Ambrose Lee now falls under the categories of "ideal" performance. Wong Yan-lung, John Tsang, Matthew Cheung, Henry Tang and Carrie Lam can be labeled as "successful", York Chow, Donald Tsang, Michael Suen, Stephen Lam and Tsang Tak-sing can be labeled as "mediocre", and Ceajer Chan, Edward Yau, Denise Yue, Eva Cheng and Rita Lau can be labeled as "inconspicuous". No official falls under the categories of "depressing" or "disastrous". Director of POP Robert Chung expects that after CE Donald Tsang delivers his policy address tomorrow, there may be another round of fluctuations in the popularity of his leadership team. The sampling error of all approval and disapproval rates is between +/-1 to 4 percentage points at 95% confidence level, while the sampling error of rating figures needs another calculation. The response rate of the survey is 68%. Points to note:* The address of the "HKU POP SITE" is http://hkupop.pori.hk, journalists can check out the details of the survey there. * The sample size of this survey is 1,010 successful interviews, not 1,010 x 67.5% response rate. In the past, many media made this mistake. * The maximum sampling error of all approval and disapproval rates is between +/-1 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 +/-1.2 and sampling error of percentages not more than +/- 4% at 95% confidence level". * 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. * 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-2009. 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:
# 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:
** Errors 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.
