Bucknor and India stats

[talksport]

Could somebody move this thread to an ISI forum ( The kolkata one)

[observer1]

Oy maan. In addition to the heart pumping cefuroxime etc, I know a bit of stats. I know that a chi-square will be less effective (i.e have a higher p value) if I use 4 and 5 instead of 80 and 100. I was just bored, and trying to do what doctors like you usually do - con the world with bs

The individual row or column values.

So in this case Fisher might make sense since the numbers are quite small yet.

A damp squib, now that we are getting serious... Analyze a 2x2 contingency table bucknor in town bucknor not in town Total wins 5 44 49 losses 6 32 38 Total 11 76 87 Fisher's exact test The two-tailed P value equals 0.5230 The association between rows (groups) and columns (outcomes) is considered to be not statistically significant.

Yeah. Ideally, at least one number should be

is considered to be not statistically significant.

As suspected, but thanks for running the numbers.:two_thumbs_up:

[The Outsider]

Yeah. Ideally, at least one number should be Okay, now you've got me curious. Do the results from the two tests converge at 5? I would expect that to be the case for this demarcation to be chosen.

If the lowest value is 5, there would be very little difference in the p values of the two Tests.

Seeing the stats trend on this thread, there's a nice test I could share with you, Shwetabh, if you are interested. Can be done on a calculator.

considering dhondy's self-reported levels of cerebral differentiation, can I safely presume the secret test on the calculator is random digital (excluding thumb) pressure to see how soon you can get pi (akin to the 'sooner or later, anyone typing on a pc at random will come with a shakespeare work')

On another thread, Observer pointed out that for comparisons to be meaningful, you need a denominator. The beauty of this test is that you don't need a denominator, as long as they are roughly equal. Say you are comparing two events (say, no of decisive Tests at Perth and MCG) ----a & b. You calculate 'z' as: z= a-b/sq root (a+b) If z is more than 2, the difference is significant (20 Denominators should be roughly equal. Beats many sophisticated tests for its utter simplicity.

A very intuitive test, Dhondy. Something which the casual glance can predict, but when asked to back up with numbers would need at least a calculator. This one can be done in the head. Not sure what you mean by,

Event rates should be fairly low.

Is it that the number of decisive test matches has to be a low percentage of the total tests as in the above example. That's what I can think of intuitively.

Yeah, exactly.
