Specify the randomization options for Create Gage R&R Study Worksheet

Stat > Quality Tools > Gage Study > Create Gage R&R Study Worksheet > Options
Select the randomization option that best describes how you want to collect your measurement data.
  • Do not randomize: Do not randomize the measurements so that the run order is the same as the standard order. The worksheet includes a column that lists the run order of all measurements sequentially (1 through the total number of runs).
  • Randomize all runs: Randomize the run order of all measurements. Each time you create another worksheet and randomize all runs again, you will have a different run order.
  • Randomize runs within operators: Randomize runs for each operator. Each operator measures all parts, in random order, for the first replicate. Then each operator measures all parts for the second replicate. For example, Operator 1 measures parts 1–10 in random order, then Operator 2 measures parts 1–10 in random order, for each replicate.
    Randomize operator sequence
    Randomly assign the operator order sequence for all the replicates. For example, suppose you have 3 operators and 2 replicates. The operator order will be random so that Operator 3 could measure all the parts in replicate 1, and all the parts in replicate 2, before Operator 1 measures the parts.

For more examples about randomizing your worksheet, go to Worksheet randomization for a gage R&R study or a Wheeler's EMP study.

Base for random data generator
Enter a positive integer to set the starting point of Minitab's random number generator. When you create a new data collection worksheet, if you want to use the same set of random orderings, set the base to the same value.
Store standard run order in worksheet
Specify whether to store the standard order of runs in the worksheet. The standard order is the non-randomized order of the runs.
