Use this screen to specify the characteristics of the sample by specifying the number of cases in each subclass.
Total Number of Cases is the total number of cases in the original table or view before you do any sampling.
To redistribute the percentage of cases, click on the Sample Distribution column in the grid and type in new values. The percentages for the new distribution must add up to 100.
To specify the same number of cases for each value of the attribute, click Equal Distribution. For example, you might want 50% of the selected cases to have SEX='Female', even though only 5% of the cases in the population have SEX='Female'.
To redistribute the number of cases, click on the Sample Count column. The total of the Sample Count column must be less than or equal to the number of cases in Total Sample.
Click Restore to return to the original distribution.
Total Sample Count is the number of cases in the sample. It is always less than or equal to the Total Number of Cases.
Percentage of Original is the percent of cases in the sample; it is always less than or equal to 100%.
The wizard uses a random seed to generate the sample. To view or change the random seed, click Advanced.
Click Next to continue.
The wizard checks that the percentages in the Sample Distribution column add up to 100. If there is a problem, you cannot go to the next step until you correct the problem.
