Create a Subset of Random Cases

These instructions describe how to create a subset of random cases selected from a source subset. For instructions on Creating a new Subset click here

To begin, click on Subsets > Random Sample.

This will bring up the Create a Random Sample from a Subset window.

The first line is labeled Input Subset. Enter the name of the subset from which you want to take the random sample. You can click on the Browse button to select the input file from a list. Notice that after you select a subset an number appears to the right. This number indicates the number of cases that are contained in the input subset.

The second line is labeled Output Subset. Enter the name you want for the new subset. This subset will contain the randomly selected cases.

The Third line is labeled Number of Random Cases. Enter the number of cases that you want selected from the input subset in this line.

After entering the required information, click on the Run button. The subset will be created and you will get a results window similar to the following.

The Results window lists the number of randomly selected cases and the name of the new subset where the cases can be found. Click on OK to close the Results window. This will also close the Create a Random Sample window and you will be taken back to the main menu. The subset of random cases is now created.

Clicking on the Cancel button at any time during this procedure will close the Create a Random Sample window and take you back to the main menu.
