# Create a cluster

Creating a [Cluster](<https://help.apteco.com/en/faststats/modelling/cluster/index.md>) uses the same basic steps as if you opened the Cluster tool direct. By generating the Cluster model through the Modelling Environment you have the benefit of using the variable association, interaction and distance matrices options to enhance the preparation stage.

1. Drag the **Modelling Environment** tool on to the workspace
2. Drag the selections on to the **Selections** tab you wish to use in the **Cluster**. Tick the boxes against the selections you have determined to be the **Base** and **Analysis** groups

   > **Note**
   >
   > A selection of all records will be generated automatically and be set to be the default Base selection. Change what is an Analysis or Base group by clicking in the cell of the Type column.
3. Click on the **Dimensions** tab and drag on the variables you wish to use in the analysis

   At this stage you can use the association or distance matrix options to determine which variables to use or how they look. Interaction variables are not allowed and don’t really make sense in a Cluster model.
4. Click the **Build** button (you can now review the Dimensions information)
5. To generate the **Cluster** click on the button and the Cluster will be generated in a separate window
6. Create the **Cluster** by clicking on the

   **Build** button in the Cluster window

## Reviewing results

This Cluster will be recorded on the Results tab of the Modelling Environment. This Results area will also record the creations of your Profile and Decision Trees during this session. Each time you build these tools a new entry will be added recording the changes and new results you have found. This allows you to create a history or development trail for your modelling. You can reopen a Cluster that you have previously created by either dragging it off the results area, or doing a right click and “View a Copy”.
