A conceptual primer on the single transferable vote – 6: Meek method
In part 5, we presented the weighted inclusive Gregory method. In that part and all previous parts, during the distribution of preferences we have ‘skipped over’ any candidates who have already been elected, as we said that to give extra votes to any of… »

A conceptual primer on the single transferable vote – 5: Weighted inclusive Gregory method
In part 4, we presented the Gregory method, which removes random effects from STV. In that part, we continued with a decision made in part 3 to restrict the ballot papers which can contribute to a surplus distribution, yielding the exclusive Gregory method.

A conceptual primer on the single transferable vote – 4: Exclusive Gregory method
In part 3, we discussed a refinement to random transfer STV, noting that even in refined form it is still subject to random effects. In this part, we introduce a method which eliminates randomness from STV completely.
For the sake of illustration, let's again… »

A conceptual primer on the single transferable vote – 3: Refining random transfer STV
In part 2, we described the original 1873 implementation of STV by Thomas Hare, noting that the method then proposed was highly influenced by the effect of random chance. In this part, we will introduce some strategies to reduce this effect somewhat.

A conceptual primer on the single transferable vote – 2: Andrae's and Hare's methods
At the end of part 1, we provided an outline of STV:

A conceptual primer on the single transferable vote – 1: Building a fair voting system
The single transferable vote (STV) is a family of multiple-winner voting systems which provide proportional representation by allowing voters to rank candidates in order of preference.
This series provides a primer on the principles of STV, from its conceptual foundations through to contemporary developments in… »
