# What does the output mean?

You can watch the Decision Tree building and investigate the results in the Tree View Panel. Note that the [Dimension](<https://help.apteco.com/en/faststats/modelling/decision-tree/example/setting-the-dimensions/index.md>) and [Base Selection](<https://help.apteco.com/en/faststats/modelling/decision-tree/example/setting-the-base-selection/index.md>) tabs are used in setting up a Decision Tree.

## Tree panel (top half)

Alternative views of the whole tree enabling the user to make selections of individual or multiple nodes.

- The tabs in the **Tree Panel** ([Tree Grid](<https://help.apteco.com/en/faststats/modelling/decision-tree/using-the-output/tree-grid/index.md>), [Box Tree](<https://help.apteco.com/en/faststats/modelling/decision-tree/using-the-output/box-tree/index.md>), [Organic Tree](<https://help.apteco.com/en/faststats/modelling/decision-tree/using-the-output/organic-tree/index.md>) and [Gains Chart](<https://help.apteco.com/en/faststats/modelling/decision-tree/using-the-output/gains-chart/index.md>)) all provide different views of the same Decision Tree.
- The [Status Bar](<https://help.apteco.com/en/faststats/modelling/decision-tree/using-the-output/change-status-bar/index.md>) at the bottom of these tabs gives a summary of either the current selection or the whole tree (if no selection is made).

## Focus panel (bottom half)

The Focus Panel provides details relating to a single node. This is referred to as the *focus node* and is highlighted with a red border in the other views.

- The **Focus Panel** provides a graphical view of the focus node, as well as a number of other views (*Node Details*, *Node Rule* and *Next Splits*).
- The **Focus Node** is either the last node which the user has clicked or the node which the mouse is hovering over, if *shift* is also being pressed.

For more details see Decision Tree: What are the different screen areas.

## Use of colour

In all the views the default colour coding used is as follows. You can alter the colours used in the main options panel (main Tool…Options menu). See *[Change the default options](<https://help.apteco.com/en/faststats/modelling/decision-tree/setting-up/default-options/index.md>)* for more details.

- **Red**: Relates to people in the analysis selection. The more intense the red, the higher the proportion of people in the analysis selection.
- **Blue**: Relates to people not in the analysis selection. The more intense the blue, the lower the proportion of people in the analysis selection.
- **Grey**: Used to show that analysis propotion in a particular node is in line with the overall data.
