Entry Section
Below
is a view of the data entry panel from the spreadsheet. In this case there are three testers, making two readings on
each of the different parts.
This panel can be somewhat confusing at first, so a review of how the sections are organized will be helpful.
The data for each tester is entered in horizontal sections.

Calculations
Because
macros were avoided, the messy details of the calculations appear in the next section. If they make one nervous,
just hide them, and go directly to the Scorecard. One may, however, find these calculations helpful. Here is how this sec-
tion is organized:
The first table in the calculations section shows the average reading for each part for each tester. Be sure and note the color-
coding scheme to keep track of the headings in the table. Headings pertaining to test conditions appear in purple. Headings
for samples appear in yellow.
