Which distribution is this...

2000-12-23 Thread Derek Ross
This is an odd distribution... I think it may somehow be related to the binomial distribution, but I'm not certain. The idea is difficult to explain, so here's a "real-life" example of generating the distribution: I have four coins in my hand. Each coin has a number on both sides. All coins have

perhaps, an example would help: let's say, 30% of population of Whoville had blue eyes, and 70% brown eyes. let's pick a few whos at random. each one, coming from the same population, has 70% chance of having brown eyes and 30% blue eyes, that's the distribution X. but the actual eyes of the act

Just reading through some notes, and I was wondering what exactly is meant by the following sentence: Every sample observation x is the outcome of a random variable X which has an identical distribution (either discrete or continuous) for every member of the populations. Thanks! b1gp1g. Sent

The Margin-of-Error Fallacy

- Forwarded message from Jake - Most of us feel that we know what "margin of error" means but to make sure we're all on the same page, let's review. "Margin of error" is a term out of survey polling that refers to the confidence we have in the results of a given survey. In general, the m

I think it would be unwise to use random sampling theory, with or without the finite population correction, to infer what the percentage of Bush and Gore votes would be among the non-machine counted votes. There were several analyses published in the press about who would have won a recount, b

A good approximation can be obtained algebraically if the model is linear, otherwise ... The only treatment that comes immediately to mind is by Alec Brownlee in his 1960 book, Statistical theory and methodology in science and engineering -- Wiley. He referred to it as using the regression line i

The Margin-of-Error Fallacy

2000-12-23 Thread Jake
This year, circumstances dictated that the US Presidential race boiled down to the results in Florida. That's where the decisive Electoral Votes were and that's where the outcome was most uncertain. Since then, Bush supporters have been insisting that all the votes have been counted and Gore supp
