After you use Calculate Gap Pools, you need to allocate the gap pools.
In the worksheet, enter the column or columns that contain the allocation weights for the gap pools.
If you enter only a lower specification for the gap, which is the default analysis, then you have either a mean pool or a variance pool, but not both. In this case, you need only one set of weights. If you enter both upper and lower specifications for the gap, then Minitab calculates a mean pool and a variance pool. In this case, you need two sets of weights, one for each pool. The weights must be between 0 and 1, and each set must sum to 1. To see an example, go to Data sets that are used in Six Sigma module help.
