Electric Vehicles are a key part of our tomorrow and how we get there. If we can get all the fossil fuel vehicles off our roads, out of our seas and out of our skies, we'll have a much better environment. This community is where we discuss the various different vehicles and news stories regarding electric transportation.

The sample size for a population of 200 million (people in the US minus children and people over 70) with a confidence of 95% and error margin of 5% is below 400.
Surveying 800 people actually brings the error margin down to 3.5%, which is extremely good in terms of applied statistics.
The only thing needed is to add 'surveyed' after the descriptor. Anything else is dishonest.
Do you think any statement which starts "x% of Americans...." Suggests they surveyed every single American alive?
Maybe they should specify "alive" though, because not telling you they're not including past Americans who have died is dishonest.
Yes. 25% of U.S. citizens linguistically means 25% of all U.S. citizens. They don't need to specify alive, because they had to be alive inorder to participate. It is not dishonest in this case because they (the original study) listed the date the survey was conducted and didn't not try to portray an old study as modern.
