Thanks

Check out Cy-Falls 2015, pg 13 for Cochran-Mantel-Haenszel tests. Very few tests are written with CMH in it. This is a national treasure If you don't have access to the test let me know.

Wright State 2015 (end section of test) and Cornell 2016 (q 20-25) are also good on general statistics. Again if you don't have access to these tests let me know.

For chi square, should we memorize parts of the chi square table?

You could probably put a table on your notesheet fairly easily. Since you would rarely have to refer to it, you can use a very small font size (like 2.5 or 3), type it into Excel, format it, export as PDF, and take a screenshot.

Thanks for the great info! For some reason I can't seem to find the tests. Are they in the archive test exchange?

I would say the most common stats are simple proportions like rate ratio or risk ratio, odds ratio, prevalence, incidence, attack rate and the like. Age adjustment shows up, and maybe Mantel-Haenszel at State and National.

Do Koch's postulates come up at all, or is that an old subject?

It came up on our Division B test last year in regionals, but I believe its fairly uncommon.

When I've seen it it's mainly just been asking you to list all of them. Last year at my Regionals they gave examples of 4 or 5 of them and asked us to name which one they best fit.

Does anyone know where I could find these tests? I don't think dcrxcode has been on since.
