Sliders and Service Increments

Nina Midgley -

Sliders are used in Simulator to enable the responden 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 the percentage increments of a slider determined

The slider scale will increase and decrease in percentage increments for Budget and Bill Simulators, or in points if you are running a Points Simulator. These increments are determined by the administrator in the admin side.

If you are creating a scale with both negative and positive increments, 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.

Example of balanced slider with increments from -50% to 50%.

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

Example of positive asymmetric slider with increments of 5% which starts at -10% and only goes to 20%.

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

Example of negative asymmetric slider with increments of 5% which starts at -20% and only goes to 10%.

 

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 'Children's' which would apply to both the items within that group: Children's Social Care, and Early Help and Schools Support. The admin might then set up an asymmetric slider for the slider group 'Community Services' 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 when a participant first arrives on the site
    • In a Budget or Bill Simulator, the '0' mark is determined by the financial information added in for each item during set up — it represents the current total spend
    • For Points Simulator, the '0' mark is the status quo, or 0 points

Example of the current total spend set on a slider item in a Budget or Bill Simulator:

This screenshot is an example of the current total spend set on a slider item in a Budget or Bill Simulator, so in this case a '0' mark would be equivalent to £72,784,000.
