Infotools Harmoni allows you to set a base to an axis, an element or multiple items. A base applied in the project tree will change the denominator when creating an analysis.
The table and graph percentages will then be calculated on this applied base and the respondents filtered on the same applied base.
1. Copy and apply a base
Instead of using the default Total the base can be forced to be some predefined value. A predefined base can be added for the whole axis or different predefined bases can be used for each element in the axis. If they exist Infotools Harmoni will always use the predefined base when calculating percentages.
You will first need to select an element or multiple elements in your project tree. The contextual option copy as base will be available under edit. Following this, you need to select the item or group of items for which you want to apply the base. The option apply base will be available under edit.
On clicking apply base, the information icon ('i' in a circle) will display next to the item. Hovering on the information icon will show information about the applied base.
In this example, we are using as base respondents whose visit length has been three nights or more.
- Select/copy as a base three elements.
- The contextual option copy as base will be available under edit
- Select the item or group of items for which you want to apply the base. The option apply base is available under edit.
- On clicking apply base, the information icon ('i' in a circle) will display next to the item.
2. Apply base to standard axes and elements
- Applying a base to an axis applies the same base to all elements.
- Applying a base to an element applies the relevant base to that item.
- You can only apply a base to the axis or the elements but not both.
- Axis base overrides what was set up on at the element level.
3. Apply base to Grids
- Applying a base to an axis in a grid applies the same base to all elements for just that axis.
- Applying a base to elements within a grid applies the same base to all axes.
- If a base is applied both to an axis and an element in a grid, the element base overrides what was set on the axis.
4. Remove a base
The applied base can be removed using remove base option under edit.
