p<0.05

We’re told early and often that this means that your data is significant. But statisticians and biologists that are statistically inclined, while tell you (and have been telling us for awhile) that this is a completely arbitrary figure. Like most tools, in statistics if you use the pvalue incorrectly you’re doing yourself and your science a disservice.

And the American Statistics Association agreed, and disagreed. Last week they released an AWESOME statement on p-values.

Read the original, or the equally excellent synopsis over at the Molecular Ecologist (I can’t give that blog enough love…)
