Allows you to control the randomization of the measurement runs of your study, either across all runs, or within operator.
Dialog box items
Do not randomize: Choose if you do not want to randomize your data collection. In this case, the standard order is the same as the run order, and both columns list all runs sequentially (1 through the total number of runs). See Worksheet randomization for examples.
Randomize all runs: Choose to randomize the run order of all measurements. The standard order of each replicate of each measurement will be randomized and given a new run order, listed sequentially. See Worksheet randomization for examples.
Randomize runs within operators: Choose to randomize runs for each operator. This choice may be useful if you want each operator to make measurements on all parts and all replicates without taking turns or waiting for the other operators. So Operator 1 measures runs 1-10 in random order, then Operator 2 measures runs 11-20 in random order. See Worksheet randomization for examples.
Randomize operator sequence: Check to randomly assign the operator order sequence. So Operator 3 may measure runs 1-10, then Operator 1 may measure 11-20, and so on.
Base for random data generator: Enter a positive integer to set the starting point of Minitab's random number generator. To generate the identical set of random orderings time after time, set the same base each time you generate a random sample.
Store standard run order in worksheet: Check to store the standard order of runs in the worksheet.
