For an interesting look at how statistics can be used to provide illusory support to a popular misconception, read this article, Cross-National Correlations of Quantifiable Societal Health with Popular Religiosity and Secularism in the Prosperous Democracies, and then read the following:

Dogma Bites Man by George H. Gallup, Jr.
I am not a statistician, so I leave it to others to interpret the original article as well as the rebuttals.
I am particularly impressed with the results of polling done in 2002, which suggested that the 10% of respondents who scored highest on "Love of God" were significantly more likely to be involved in service to the poor and suffering, and believed that all people are loved by God and therefore we should also love them (Dogma Bites Man).
