MUST READ: Census/Exit Poll Gender Vote Probability Analysis
Edited on Sat May-28-05 11:51 AM by TruthIsAll
           Election Probability Analysis 
                   based on
 Census Gender Voting Statistics and National Exit Poll Pct.

At 12:22am on Nov.3, there were 13047 respondents in the
National exit poll.
Kerry had 54% of the female vote and 47% of the male vote.
Bush had 45% of the female vote and 52% of the male vote.

At 1:25pm, there were 13660 respondents in the final poll.
Kerry had 51% of the female vote and 44% of the male vote.
Bush had 48% of the female vote and 55% of the male vote.

The total vote was recorded as 122.26 million.
But according to the Census, 125.74 million voted.
How did 3.5 million votes go uncounted?

Census Gender statistics matched Exit Poll weights to within
0.5%:
	Female	Male	Votes (000)
Exit	54%	46%	122,267
Census	53.51%	46.49%	125,736
Vote	67,281	58,455	

The tables below give various scenarios  and probabilities
using Census gender voting statistics and the 13047 exit poll
voting percentages.			

Kerry ties Bush when he gets 52.75% of the female vote and
45.75% of the male vote. This is the breakeven (B/E)
scenario.			

The probability that Bush would at least tie in the popular
vote is 0.71% (1 in 140).

The probability that Bush would go from 48.25% in the poll to
his recorded vote of 50.25% is
 1 in	2,083,900.
			
The probability that Bush would go from 47.75% in the poll to
his recorded vote of 50.25% is
 1 in	485,887,839

1. Typo: Bush got 50.75%, NOT 50.25% of the recorded vote
Edited on Sat May-28-05 01:05 PM by TruthIsAll
The probabilities are correct.

The sentences should read:
The probability that Bush would go from 48.25% in the poll to
his recorded vote of 50.75% is
1 in 2,083,900.

The probability that Bush would go from 47.75% in the poll to
his recorded vote of 50.75% is
1 in 485,887,839

2. CHECK OUT THE TINY CENSUS MOE'S
Edited on Sun May-29-05 01:05 AM by TruthIsAll
The total us vote of 125.736 mm is correct to within 0.30% at
the 90% confidence level (+/377,000 voters).

Note how close the given MoE is to the calculated MoE (within
0.02%)using the formula:
MoE= 1/sqrt(n), where n= population size (000)



				Census		MoE		
U.S.	Total	Pct	Pct	MoE	  (000)	1/sqrt(n)	Diff	
.Total	125,736	58.3	100%	0.30%	377	0.28%	0.02%	
								
.Male	5
       8,455	56.3	46.49%	0.40%	234	0.41%	-0.01%	
.Female
	67,281	60.1	53.51%	0.40%	269	0.39%	0.01%	

.White alone
	106,588	60.3	84.77%	0.30%	320	0.31%	-0.01%	

..White non-Hispanic alone

.Hispanic (of any race)

8. Nice job...I was waiting to see the gender weighting explained.
Hmmmm....so were these "reluctant" responders all women? :eyes:

This is truly hilarious.....We have an argument here folks that has been beaten into the ground, mutilated, crucified, and Mitofsky still brings it back to life even though the government basically said "Nope, there is no such thing."

Nothing to see here everyone! :toast:
