54% of drivers don't pass through ERP gantries on the way to work
By Maria Almenoar
EACH time the tolls on Singapore's roads rise, a chorus of complaints sounds from drivers across the island.
But the reality is that less than half of all motorists pass through Electronic Road Pricing (ERP) gantries on their way to work.
A Singapore Press Holdings survey of 295 motorists found that 46 per cent fork out money for the privilege of driving on the island's roads.
Of those, about 70 per cent pay $3 or less every morning.
The survey was done over three days in mid-November, about two weeks after ERP rates were raised by 50 cents.
That brought tolls on the Central Expressway from the Pan Island Expressway to $5 between 8.30 and 9am - making it Singapore's costliest road. "
Came across the above while surfing net for my daily dose of news..
When i was in poly.. my teacher taught me that for any survey to be meaningful, the following should be adhere to as closely as possible..
1) the sample size should be large enough.
2) the demographic of the sample size should be resemble the survey targetted audience as closely as possible.
3) the purpose and intent of the survey must 'highly visible' from the onset.
After reading the article, I wish my teacher taught everyone how to do a proper survey..
