About this Quebec poll from Ipsos
This Quebec poll was fielded by Ipsos in May 2018, with a middle field date of May 1, 2018. The poll collected data from a total sample of n=2,001 Quebec respondents via an online panel.
The margin of error for an online sample is not applicable.
For comparison purposes, a random sample of this size would yield a margin of error [moe] of ±2.2%, 19 times out of 20 (for entire sample only) around the 50%-mark.
If we compare these national numbers with the previous poll from Ipsos (February 2018), the Coalition avenir Québec is up one point (variation smaller than moe), the Liberal Party climbs two points from 30% to 32% (variation similar to moe), and the Parti Québécois loses three points from 23% to 20%.
