how is there a difference?
what the hell are you talking about?
well at least you aren't a fucking idiot pretending to be hot shit like raven. Dude probably took 1 probability course and maybe 1 statistic course in college and dind't even pay attention or else he wouldn't have been so fucking stupid about this. Now he thinks hes hot shit. Seriously, what a retard.
False negative = P( test says negative | person is positive )
i.e. the odds the test fucks up and says negative when it should have said positive
False Positive = P( test says positive | person is negative )
i.e. the odds the test fucks up and says positive when it should have said negative
Darkstrand, backpedal harder, you have a ways to go.
this is right. it would have been more complete if i said it also depends on the sensitivity & specificity of the test (which are not defined simply by the accuracy of the test).depends on the number of mormons in the US.
The answer is about 65%
If your test is 95% accurate, then the odds of a random American being a mormon are only 26% when the test says they are.
Aww, another moron ran away with his tail between his legs.
Do you feel stupid Darkstrand?
this is right. it would have been more complete if i said it also depends on the sensitivity & specificity of the test (which are not defined simply by the accuracy of the test).
this is not true. your problem is that accuracy is the percentage of correct decisions, True Positives and True negatives. the remaining 5% is then the percentage of incorrect decisions. however, as darkstrand pointed out, incorrect decisions can be either false positives or false negatives.
you made the assumption that all the incorrect decisions were false positives, which in general is not true.
When did I make any such assumption? I said that with 5% of the population, the test returns the incorrect result. What is so difficult to understand here?
False positive rate = false negative rate = 5%.
Don't propogate stupidity.
And watch the video I posted.
how on earth did this thread get here?
