That's exactly what standard deviation is for, to know the probability (or occurrence) of a given situation. A broadly spread dataset is different from a tightly grouped dataset, and that's what standard deviation tells you. Your criticism is already included in the model. The way I used it is in proper context, so it makes sense. > The statistics are slippery. The extremes don't make the case.

What I did includes everything you're thinking about and more. _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA)
