Raw Data Worksheet

The Raw Data worksheet holds only the raw data and a linked cell displaying the overall mean of the data.  The sheet is left deliberately uncluttered, with the data collection plan being common to both the R&R and W-L approaches.  The layout we have chosen is to have the parts arranged vertically, and the operators arranged horizontally (similar to Barrentine’s layout).

Note: If you are copying and pasting the data from another worksheet or application remember to use Paste Special Values if you want to preserve the formatting of the cells.

Note also that the terminology used here (Operator, Test) is different to that in the AIAG manual (Appraiser, Trial).  This can be changed easily using the Preferences option.
