Sliders and Service Increments

Nina Midgley -

This article is about sliders which are used in Budget Simulator to enable the respondent to change the spend/saving allocation for the different Slider Items. The slider has different increments, set up by the admin, and the participant moves the slider to the desired increment.

What is a slider? 

Sliders are the interactive feature which allow participants to increase or decrease spending to affect the total budget, and compare consequences

 How are the percentage increments of a slider determined? 

The slider scale will increase and decrease in percentage increments. These increments are determined by the administrator in the admin side.

The increments MUST run from negative at the left hand side of the slider (top of the scale in the admin side) to positive at the right hand side (at the bottom of the scale).

Slider terminology

1. Balanced Slider: Where there are an equal number of increments on both the positive and negative sides of the slider, balanced at 0 in the middle.

2. Asymmetric, Positively Biased Slider: Where there are more increments on the positive side of the slider

3. Asymmetric, Negatively Biased Slider: Where there are more increments on the negative side of the slider

 Limitations of the sliders

  • Sliders can be structured differently from one group to the next, but not per item i.e. they will stay the same within groups.

Using the structure below as an example, an admin could set up a balanced slider for the slider group Leisure, which would apply to all the items within that group; Library Service, Sport and Leisure, Parks and Gardens. The admin might then set up an asymmetric slider for the slider group Planning which would apply to all the items within that group.

  • There is a limit of 11 increments on any one sider, and it is mandatory for one of them to be '0'
  • '0' will be the neutral point at which all sliders are set to when a participant first arrives on the site.
  • The '0' mark is determined by the financial information added in for each item during set up. It represents the current total spend.
