Données tirées du sondage : Religion and faith in Canada today: strong belief, ambivalence and rejection define our views (Religion et foi au Canada aujourd’hui : la croyance forte, l’ambivalence et le rejet caractérisent nos opinions), Angus Reid Institute ; en particulier la page 13 du rapport complet en format PDF.
J’ajouterais la méthodologie:
The Angus Reid Institute conducted an online survey from March 4-11
2015, among a representative randomized sample of 3041 Canadian
adults who are members of the Angus Reid Forum. For comparison
purposes only, a probability sample of this size would carry a margin of
error of +/- 1.8 percentage points, 19 times out of 20.
The research was self-commissioned and primarily paid for by ARI,
with a contribution from Dr. Reginald Bibby and the University of
Lethbridge. Dr. Bibby also contributed significantly to the research and
analysis of this study. Detailed tables are found at the end of this
release.
Ça permet de nous situer. Certains études tirent des conclusions avec un échantillonnage trop faible.
