how about using a little common sense. there are 330,000,000 people in the USA. most national polls use 800 to 1200 people in their samples.
1000 out of 330,000,000 is what % ? can you do the math?
I know they claim to use "representative" samples. but come on, its a game.
Total ignorance of statistical sampling techniques
More reasons why Republicans lost in 2012
your ignorance is only exceeded by your arrogance. go to your local library, pick up a stat 101 textbook. Look up "representative sample".
It will tell you that for a sample be significant it must be a least 5% of the population.
the pollsters have tried to come up with some mumbo jumbo by which they claim that they pull samples that include all elements of the population and thereby overcome the math.
Its bullshit, the math does not change, they cannot change it. Polls are being used to influence political opinion, not to report on it.
if you want to buy into that fraud, go right ahead.
No statistician would give you an absolute 5% sample size because your required percentage decreases as your sample size increases. A statistical sample of 1000 can be very telling in estimating a population assuming statistical randomness
You are assuming only a single sample is made. Multiple polls are conducted week by week. If I take a 1000 point sample one week and it shows Democrat 54% and Republican 46% and the next week it shows Republican 54% and Democrat 46% then I know that my sample is not representative of the population
But if my samples of different populations of 1000 show consistently that Democrats are maintaining a range of 52%-56%then I know I am accurately gauging the whole population with +/- 2%

since 5% of 20 is 1, does that give you a valid sample? of course not, the bigger the sample the more accurate the result.
