Discussion > Will Steffen deals with "skewed" poll data
Wow.
Removing data because it's confounded with a separate issue (party politics) and thus is misleading is quite justifiable.
The error is in only assigning one side of the debate with the separate issue.
If they had concluded "this survey means nothing as it's all too politicised" then it may have been fairer and more accurate.
It may even have helped in creating a more accurate survey.
M Courtney, shouldn't we consider the goal of the study?
It seems to me here they just wanted to gauge where public opinion sat, not gauge the objective value of the proposal. I can't see how voting intention comes into it then. And poll rigging would be a separate issue, which wasn't suspected.
Here's a jocular follow up by one of our conservative columnists

I think that similar logic is used by Brand (Russel), Church and others when protesting about the "Nasty Tories" getting into power. With the electoral system in place the largest group wanted the policies of the party in power, including keeping more of their money to spend how they see fit.
There seems to be, in my view, a difference between those on the right and those on the left. When a result goes against what those on the right wanted they get on with making the best of the situation they find themselves in, those on the left take to the streets in the hope of putting right the grave error committed by the uncaring/ill informed/stupid voters.
Will Steffen, one of Australia's climate guys, from his bio:
He's co-authored a recent article pertaining to - not climate - but an urban planning matter. A recent poll showed a majority of residents didn't support a new public transport proposal. This was the wrong result, hence a reanalysis was in order.
Light rail poll: What do the numbers really say? (June 25, 2015) "We reanalysed the numbers in the light rail poll and got a very different picture, write Will Steffen and Barbara Norman."
So what did reanalysis involve? Let's break it down.
They identify that party lines are highly correlated with responses - conservatives (32 %) don't want it, progressives/other want it. Urban planning, go figure.
Political affiliation of sub-groups can effect the result, or "skew" it in Will-speak, which can be "misleading" because, eh, because that sub-group - I mean the skewed one, not the others which aren't skewed - the skewed sub-group constituting 32 % of polled residents generates a misleading impression because... hey look, is that Mel Gibson riding a unicycle?! *runs*
We removed every single response of those who support the current elected government, because they're skewed!
After removing those we disagree with we get the result we want to see.
Statistics!
