Globe and Mail, Sept 13, 2011, “‘No major issues’ with 2011 census, Statscan declares“
How can self-selection biased avoided by a volunteer survey? How do we know the data is “clean”?
Sadly, I have little trust in the current government appointed Chief Statistician of Canada. I want to hear what Munir Sheikh, former Chief Statistician of Canada, have to say first?
P.S. In a just society, we have to care about people who don’t fill in a volunteer survey (because they are poor, don’t have time, or less educated, etc). The less fortunate ones are often under represented.
