that way, they can see that using the p value is just a shortcut way to make the decision withOUT having to look up the CV (or vice versa?)
but, it amounts to the same decision ...
i didn't even think anyone really did that anymore ... and certainly software could care lessOf course, these approaches yield identical answers on problems. I like it because it bridges the gap between the old style and the current prevelance in use of computers. The traditional approach has advantages because it is graphically easy to illustrate. The P-value approach has value because it is more like what students may encounter in using a computer to calculate a stat and is increasingly what is reported in journals (less and less are we seeing p<.05 in lieu of p=.028, for instance). The linkage to probability is also more emphasized compared to the traditional approach where the probabilities are getting somewhat hidden behind veils of alpha, t, and z.Now, if we can only get over the arbitrariness of the n<30 cut-off for use of t vs z and teach: use z when you know sigma and t when you don't. (Triola, as much as I like some of its choices, still retains this) <sigh>
