32 is statistically significant. I had the same issues with it when I learned it too.
What’s the margin of error and confidence level?
Margin of Error between 8-10.
Confidence Level - ~90%
Are we being civil now? Did you take your meds?
A 32 person sample out of a 20,000 person population with a 90% confidence level has a 15% margin of error.
That's horrible.
Going back to the John/Steve election, if the true position of the 20,000 voters was John 55% and Steve 45% and you ran a 32 voter pre-election poll 100 times, 90% of the polls would come back with John getting somewhere between 40% and 70% of the vote and Steve getting between 30% and 60% of the vote.
The other 10% would come back with fluky results outside those ranges. And you wouldn't know which ones were the flukes.
It's a worthless sample that tells you nothing.
