Sampling from a Complex Design
Define Unequal Sizes

Define Unequal Sizes dialog box
The Define Unequal Sizes dialog box allows you to enter sizes on a per-stratum basis.
Size Specifications grid. The grid displays the cross-classifications of up to five strata or cluster variables—one stratum/cluster combination per row. Eligible grid variables include all stratification variables from the current and previous stages and all cluster variables from previous stages. Variables can be reordered within the grid or moved to the Exclude list. Enter sizes in the rightmost column. Click Labels or Values to toggle the display of value labels and data values for stratification and cluster variables in the grid cells. Cells that contain unlabeled values always show values. Click Refresh Strata to repopulate the grid with each combination of labeled data values for variables in the grid.
Exclude. To specify sizes for a subset of stratum/cluster combinations, move one or more variables to the Exclude list. These variables are not used to define sample sizes.
