From The Faster Times:
This morning, readers of the Toronto Star woke up to a new fact. On page GT1, Urban Affairs Bureau Chief David Rider writes that Rob Ford, the right-wing populist candidate for the mayoralty of Canada’s largest city has caught up to George Smitherman, the centrist candidate of Toronto’s liberal establishment.
How does The Star know? It’s simple. Lorne Bozinoff, president of the little-known polling firm Forum Research, Inc. told them. Forum Research conducted a telephone poll of 405 Torontonians over the weekend and supplied the results exclusively to the Star.
The Star gives the results as a percentage of decided voters.
George Smitherman: 29%
Rob Ford: 26%
Sarah Thomson: 17%
Joe Pantalone: 12%
Rocco Rossi: 10%
Giorgio Mammoliti: 4%.
The Star then informs that since the poll’s margin of error is 4.9%, 19 times out of 20, Ford and Smitherman are statistically tied. This is problematic. Since Bozinoff informs that 44% of voters are undecided, that means that only about 227 of the 405 respondents actually expressed a preference, and that the margin of error of the results of this subsample is considerably higher.
For a margin of error of 4.9%, all opinions should be represented, which would look like this:
George Smitherman: 16%
Rob Ford: 15%
Sarah Thomson: 10%
Joe Pantalone: 7%
Rocco Rossi: 6%
Giorgio Mammoliti: 2%
Undecided: 44%
Bozinoff not only supplies this article’s facts but also the bulk of its analysis. He claims that it shows, “It’s a dogfight between Ford and Smitherman — they are well ahead of the others.”
This is demonstrably false. Since a poll’s swing can be either plus or minus, it becomes clear that the real story is that no candidate has any significant public support, and that five months away from election day, all the candidates (even Mammoliti), are within striking distance of one another.
Bozinoff also makes a comment about Ford’s support in the area of Etobicoke. Given that Etobicoke represents 13% of Toronto’s population, we can assume that it represents 13% of a diligent pollster’s sample. In this case, that would be about 53 people. That is a very small number of opinions from which to be drawing conclusions so confidently.
All of this makes the critical reader want to take a closer look at the poll’s results. What were the questions asked? In what order? And what is the demographic makeup of the sample? The Star has not made this information available to its readers, and a visit to forumresearch.com turns up no data either. Readers of the Star (including the author) are left having to take these opinion facts on faith.
In the Star’s article, David Rider proves himself an uncritical reporter, and Lorne Bozinoff a pollster with a poor command of his own numbers. They do not inspire trust.
This inaccurate and incomplete piece of journalism is a disservice to the city of Toronto. It can be argued that it does more to shape public opinion than it does to reflect it. To defend its credibility, the Star must make the full results of its polls available to the public and explain why it has printed and distributed these errors to hundreds of thousands of people.
