Systematic Random Sampling

This node computes and creates a new output data spreadsheet consisting of all selected variables and a random subset of the cases.

General

Element Name	Description
K value	Specifies the common distance between values selected from the original dataset. For instance, if you enter a 5 in the K value box, a case within the first five cases will be randomly selected and then the subset will be completed by selecting each fifth case in the spreadsheet after the originally selected case.

Element Name	Description
Subset variables downstream	This node will create a data spreadsheet for further subsequent analyses. You can either create a subset of the variables, retaining only those that were selected for the analyses (select Yes), or you can 'carry along' all variables from the original input data source.
