tuning numbers to make them sing
Put together a fairly good statistical analysis for a problem at work today; luckily, it came out in our favor, if I have not done something colossally stupid like set the wrong null hypothesis. I am under the impression that H0 should always assume no intervention, no change, the commonsense default assumption... but doubts creep in, when the no-change state is what I was hoping to see. Is there any particular rule of thumb I didn't hear about in my intro class?
Stats, like proofreading, is exactly the sort of highly nitpicky enterprise that makes me do a little chairdance of delight. I think I started to like it a whole lot around three years ago, though I am still only middling good at it.
On that note, I am now looking for a decent above-introductory-level book on how and when to do varying types of analyses -- chi-square, ANOVAs, variations on the Student t-test, that sort of thing. any ideas?
Now taking a break from practicing Stupid Presentation I Never Wanted to See Ever Again. Hopefully after tomorrow I really won't.
