Do you think the general public understands what percentage means?

I have run into this a lot recently. People just don't seem to "get" the concept of percentage. I just had my cousin, who has a university degree, text me asking "What is 20% of 128,000?" Seriously? One of my roommates also always asks me what her grade is if she got x out of y and it's worth z% of her grade.

This worries me, because when we talk about things like the economy growing 3% or getting a return of 7% do these people have any idea what we're talking about?

Sooo, are you complaining? You can do something that others can't, and you want them to have this gift?

Survival of the fittest. Do not try to save everyone.

For the purposes of this thread, the "general public" is a random sampling of adults between the ages of 18 and 80 living in North America.

What % of this population are you using for your sample?

From the looks of it...

I'm not sure if you could call it "understand" or not. However, the vast majority of Americans cannot do computations on problems that involve percents. i.e. If something's on sale for 25% off, most Americans could not tell you the final price. And, if you're convinced they can, then a second example is figuring out how much tax there is on a $70 item, given a sales tax of 5%, 6%, 7% or 8%. (all simple mental problems.)

Your sales tax example is definitely true. Most cant even throw out an estimate.
