As you already know, you need to refine the list of characteristics before it can become
the first version of the Preliminary Field List. Remove all duplicate characteristics, delete
itemsthatrepresentthe
same
characteristic,andrefinethoseitemsthathavegenericnames.
(Remember the problem with the characteristic called “Name”? If you find such charac-
teristics, now is the time to resolve them.) Next, review all your samples and determine
whether they contain characteristics that do not currently appear on the Preliminary Field
List. Add to the list any new characteristics that you find. When you complete these tasks,
you have the first version of your Preliminary Field List.
Now you remove all the calculated fields from the Preliminary Field List and place them
on their own list; this becomes your new Calculated Field List.
Figure 6.23
shows a
small
portion
of your final Preliminary Field List and Calculated Field List.
