This is no different from a student marking his or her own exam paper. I would be very willing to be one of your volunteers.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-11957101.post-39703205803838121352010-03-12T23:50:26.142+08:002010-03-12T23:50:26.142+08:00The way the survey results are reported is not cre...The way the survey results are reported is not credible.If you want to understand why, have a look at this url.<br /><br />http://www.lta.gov.sg/images/PTCSS%202009_Annex-A.pdf<br /><br />The satisfaction score for each question was measured using a 10 pt scale. If you look at the mean score, the mean score averages between 6 to 7. The % satisfied is however very high.<br /><br />The classification of "satisfied" is not provided in the release. Based on the numbers, it is likely that as long as a person gave a score from 6 to 10, he is classified as "satisfied".<br /><br />This is a non-standard methodology in survey research. It inflates the results as it groups "indifferent" respondnents with the "satisfied" respondents. A more common grouping is<br /><br />8 to 10 Satisfied<br />6 to 7 Neutral<br />1 to 5 Dissatisfied<br /><br />Even using this highly questionable methodology, we see some alarming results. At the bottom of the release, we see a table on crowdness. On a 10 point scale, almost 50% of respondents gave a score of 1 to 5.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-11957101.post-60834059243757668842010-03-12T16:19:48.188+08:002010-03-12T16:19:48.188+08:00Thank you for pointing the error.
