Most of us have a vague idea of how you might go about predicting the result of
this week's general election:
go out and ask a large and random collection of
people who they intend to vote for. The share of the vote each party
gets in your sample of people reflects the share of the vote you can
expect nationally.</p><p><a href="https://plus.maths.org/content/how-predict-election" target="_blank">read more</a></p>https://plus.maths.org/content/how-predict-election#commentsBayesian modelelectionvotingTue, 05 May 2015 10:15:49 +0000mf3446362 at https://plus.maths.org/contentElection perfection?

<p>When you try to put democracy into action you quickly run into tricky maths problems. This is what happened to Andrew Duff, rapporteur for the European Constitutional Affairs Committee, who was charged with finding a fair way of allocating seats of the European Parliament to Member States. Wisely, he went to ask the experts: last year he approached mathematicians at the University of Cambridge to help come up with a solution. A committee of mathematicians from all over Europe was promptly formed and today it has published its recommendation.</p>

Tonight, in the final televised debate ahead of the election, the three main party leaders will talk about the economy, the recession, public sector debt, spending or cuts, and more. All will use statistics to back up their points or to pull apart their opponents' arguments. But how can we work out whether to believe the figures and what do they really mean?

<p>One advantage of the UK voting system is that nobody could possibly fail to understand how it works. However, the disadvantages are well-known. Differently sized constituencies mean that the party in government doesn't necessarily have the largest share of the vote. The first-past-the-post system turns the election into a two-horse race, which leaves swathes of the population un-represented, forces tactical voting, and turns election campaigns into mud-slinging contests.</p>
<p>There are many alternative voting systems, but is there a perfect one? The answer, in a mathematical sense, is no.</p>
