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>It's just over a week until the general election and at this stage you'd be forgiven for feeling sick and tired of it. There is, however, an interesting bit of maths behind voting that is fun to think about.</p><p><a href="https://plus.maths.org/content/election-perfection" target="_blank">read more</a></p>https://plus.maths.org/content/election-perfection#commentsArrow's theoremelectionFP-top-storyvotingvoting systemsWed, 29 Apr 2015 09:19:47 +0000mf3446361 at https://plus.maths.org/contentMaths in a minute: Arrow's theorem

<p>Is there a perfect voting system? In the 1950s the economist <a href="http://en.wikipedia.org/wiki/Kenneth_Arrow">Kenneth
Arrow</a> asked himself this question and found that the answer is no, at
least in the setting he imagined.</p><p><a href="https://plus.maths.org/content/maths-minute-arrows-theorem" target="_blank">read more</a></p>https://plus.maths.org/content/maths-minute-arrows-theorem#commentsArrow's theoremelectionvotingvoting systemsWed, 29 May 2013 12:28:03 +0000mf3445861 at https://plus.maths.org/contentWhich voting system is best?

Much criticism has been levelled at the US voting system, and with this being election year, we're bound to hear more of it. In this article <b>Steven J. Brams</b> proposes an alternative voting system that could help make things more democratic. </div>

<h3>Election issues</h3>
<p>Whenever major elections come around public attention swings, albeit briefly, to a mathematical aspect of democracy: how to devise a voting system that reflects the true "will of the people".<p><a href="https://plus.maths.org/content/editorial-7" target="_blank">read more</a></p>48Arrow's theoremCondorcet paradoxCondorcet winnereditorialelectionvotingvoting paradoxvoting systemsSun, 31 Aug 2008 23:00:00 +0000plusadmin4904 at https://plus.maths.org/contentEditorial
