Hello Jerry:

Actually the graphs and tables are still quiate useful
for checking and cutting down orders of magnitude
errors. Although I graduated in 1985, we civils used
them extensively back then and still use them today
when we've got to explain ourselves to a lay audience.
 While it's great to get precise solutions with
today's calculators and computers, it's much easier to
display how things relate to the variables with a
graphical approximation. My assumption for ROV folks
and the like, it's best to suppose that they are not
particular comfortable with computers and statistics.
If they aren't comfortable with an approach, they
probably won't use it.

To Kathy, perhaps it might make more sense if you
think of having to present a scatter graph to an
audience. While it certainly would be more precise if
you used a direct numerical approach to find the trend

in the data, it's so much clearer of the data points
are plotted and then a line is drawn showing the
trend. In this case the audience is likely math
phobic ROV's. Got to go.
