Galaxy 50-50

A Galaxy poll is out this morning with the headline result 50-50. The aggregation is unchanged, with the Coalition on 49.9 per cent.

This aggregation assumes that the tendencies of pollsters to lean one way or the other collectively cancel out, that is to say they sum to zero. A more detailed explanation of the data aggregation process can be found on this page.
