F-statistics calculation:
Note that for each given group (initial group of , say 5, samples, or a subsequent resampling group of, say 5 samples) this F-statistics uses all samples in the group to generate one value – this represents the relative difference (of means) between the (5) samples.
- Check these JS ANOVA source code packages for the calculation of the F-statistics
- First Choice: http://www.jstat.org/ (see attached)
- Alternatives: view-source:http://home.ubalt.edu/ntsbarsh/Business-stat/otherapplets/ANOVA.htm
·F-statistics <--> P-value 1-1 correspondences are computed by the Distributome F-statistics calculator

The Web-app “Inference Plot” tab does not change – it still shows the overall distribution of p-values and a highlighted vertical bar indicating P_o (corresponding to the initial F_o statistic for the initial group of (5) initial samples).
