Statistical rules of thumb Gerald van Belle
Publisher: Wiley

MLB Average/Rule of thumb: .290-.300 depending on the year. That's not a substitute for judgment. That's really high, probably unsustainably high, and he probably regresses statistically in 2013). So statistics can play a very useful role in testing these rules of thumb, and sometimes things which you think are working are not actually working. As a rule of thumb, this means that your sample size multiplied by your proportion estimate is greater than ten, and that your sample size multiplied by the opposite of your proportion estimate is also greater than ten. This workshop will use iNZight visualisation tools and other simulation activities to build a conceptual understanding of margin of error, and the “rules of thumb” for testing claims in statistically-based reports. Some of your assumptions about your system are always wrong. But that's a complement to judgment. The P-Value: What it Really Means. The P-value is one of the biggest sources of confusion in statistics, and it's not uncommon for researchers to use the wrong definition: not when they compute it, but when they think about it. Whether or not you know how to use statistical tools, this is a good rule of thumb because the fact is, you never know everything that's going on.
