Have you wondered which opinion poll is more correct, when two pollsters point in different directions?

My editor at Decoded Science asked my that question when a Gallup Poll and a Rasmussen Poll disagreed recently. My response is found in my recent online article, “How Statistics May Help Select a Reliable Pollster“.

Can Statistics Decide between Gallup versus Rasmussen?

My article tries to distinguish what can and cannot be determined by statistics. It includes a pointer to another writer’s article; she speaks knowledgeably about the different methodologies behind Gallup and Rasmussen.

As always, the American presidential election is a hot topic in the USA. Opinion polls might guide the politicians in deciding what policies or slogans should be embraced or shunned.

It’s important to ask “How accurate has this pollster been”? Mathematically, that is the guide for a statistician in deciding which results to believe.

Further Publicity for Statistics about Opinion Polls

As is customary, I also publicize my article in my Xanga blog (”Presidential Pollsters versus Statistics“), while my Blog of Writing offers a complementary writing tip in “Preview of Statistics to Pick Pollsters“.
