Ipsos Reid has posted their source for the November 12 survey.
Ipsos’ press release can be found here (PDF on Ipsos’ site, Local Copy). The source document they attached is here – (Local PDF copy).
Of particular note:
1. The “Decided voters” base was 701 people surveyed; so 100 (12.5%) were undecided.
2. There was some weighting performed on smaller sample sizes – for example, while the Lower Mainland had 443 surveyed, it counted for 401 people; while 96 people on the Island were weighted as if 124 were surveyed. I am not concerned with the downsampling, but the upsampling of the Island residents would result in more statistical error.
I really appreciate the granularity of the data that Ipsos provides; it is a lot better than Angus Reid.
