"Harris Poll confusing to Americans," reports Harris Poll

While looking for some important stuff on the Harris Poll website (okay, incidence of sexual encounters with garden furniture), I couldn’t help but notice this absolute gem of a poll results title:

“Margin of Error”, When Used by Pollsters, Is Widely Misunderstood and Confuses Most People

Yeah, I thought it was a link to an Onion story too.

In other news, Really Not All That Bright also reportedly confused by terms like “margin of error”.

Despite having taken Scope and Methods of Political Science twice.

It’s just like the old joke of the statistician asking the client “What would you *like * the survey results to be?” and having a means to mash the data around to fit.

For several years I was an aptitude testing specialist with a government agency. When we issued test scores, the scores were reported twice: the achieved score and the score plus the standard error of measurement. More than once, people called me to ask whether these acknowledged “errors” invalidated the test scores.

Wait, I’m confused…

What do people THINK that +/- 3% means?

Plus divided by minus times three percent?

Plot the curve then derive the data. :cool:

I’m pretty sure they understand that means the survey is accurate to a range of six per cent.

I think the point is they don’t understand why.
