The Split by Attribute task is used to split a data node into different nodes based on the groups in a categorical attribute, each data node only includes the samples/cells from one group. It is a more efficient way to filter your data if you plan to perform downstream analysis on each and every group separately in an attribute.

Click on the data node and select split by attribute from the Filtering section in  task menu (Figure 1).

Select the attribute to split the data on. In this case, data will be split according to the Age attribute (Figure 2).

Result of the split by attribute task will be two separate data nodes, each contains samples from one age group (Figure 3).
