Define Unequal Sizes

Define Unequal Sizes dialog box
The Define Unequal Sizesdialog box allows you to enter sizes on a per-stratum basis.
Size Specifications grid. The grid displays the cross-classificat ions 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. Variablescan be reordered within the grid or moved to the Exclude list. Enter sizes in the
rightmost column. Click Labels or Val ues to toggle the display of value labels and data values for
stratification andcluster 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. Tospecify 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.
