Statistics help please Right, I'm doing an audit at the moment, comparing a procedure we do to others that have been published. From 19 cases, we have a success rate of 73.3 %. Statistically, is this significantly different to 90% given the small numbers, and, what are the confidence intervals? Is Student T test the right one to use? Cheers guys
I'm no statistician (as you may have guessed) but is that not just for doing the test though? My real problem is knowing which one to do....T test is for groups of data between population, and I don't think that's appropriate in this case
It wasn't chi squared This should be such a simple thing to do, and I'm totally stumped. Wish I'd done A level maths now.
