rehmwa 2 #51 May 4, 2006 QuoteUmm - the sample size is millions of births. The 4 or 6 in 1000 is the RATE of infant mortality. Your abject groveling apology will be accepted. Yeah, I knew that, but the blanket statements are still crappy ways to look at data. And t-test of rates still require the total sample size and are much harder to run. (And some countries aren't even millions in total population,) But I'll run it again to see if it works with a 'reasonable' sample base. ---the 0.4% vs 0.6% difference is significant at a base sample size of just under 10,000 (when tested as a proportion instead of a rate (at 95% confidence). In fact, a direct sample size analysis would say 1060 sample size (which makes more sense to me) At these samples, the results will normally be identical with either test of rates or proportions). My abject apologies. For large countries, this is extremely likely to be a real difference and not natural variation. No groveling will be forthcoming as the original poster used no logic, only personal gut and bias in coming to his conclusions, though. The only thing in question at this point is the data collection definition. For samples around 9000 or less, .4% vs .6% isn't meaningful Sample X N Sample p 1 36 9000 0.004000 2 54 9000 0.006000 Difference = p (1) - p (2) Estimate for difference: -0.002 95% CI for difference: (-0.00406060, 0.0000606049) Test for difference = 0 (vs not = 0): Z = -1.90 P-Value = 0.057 ...

I think that makes the sample size excellent, considering that all births and deaths are recorded. I case you haven't noticed, 4 million is somewhat larger than your 9,000 value.

Lindsey 0 #56 May 14, 2006 Had to dredge this back up to share an ER story from tonight. Midnight. A mom brings her 7 y/o daughter into the ER with the following complaint: "Mother states that every night for at least 1-2 months, her daughter cried complaining of abdominal pain. She eats nothing but junk food and only has 1 bowel movement a week. Two months ago she was treated by her pediatrician for a possible urinary tract infection, but mother did not keep her follow-up appointment, and the patient is no better." Your tax dollars at work. linz-- A conservative is just a liberal who's been mugged. A liberal is just a conservative who's been to jail Quote Share this post Link to post Share on other sites

Lefty 0 #58 May 15, 2006 QuoteQuoteQuoteThey can drive whatever the fuck they want as long as I pay $10 for the doctor visit and $20 for name brand prescriptions.... Bear in mind that under our system, I pay $0 for doctor visits & $0 for prescriptions. $0 for hosptial visits. $0 for operations. $0 for CT & MRI Scans. Etc... And... Given that my present condition is perhaps chronic, I DON'T have to worry about my "Medical Insurance" NOT BEING RENEWED!!! I only have to worry about getting better. Not whether I can afford treatment or medication I need! Not whether my insurance company will continue to make a loss on me year after year! Like I said, being ill is a singularly crap time to have to worry about money! Mike. And how much of your current tax burden goes to pay for that? I think the question is, how much of other people's tax burden goes to pay for that? *Edit* SpellingProvoking a reaction isn't the same thing as saying something meaningful. -Calvin Quote Share this post Link to post Share on other sites
