The dashboard provides a visual representation of how your stock groups compare against each other.
The colours on the dashboard give you a quick and easy representation of which of your stock groups have the highest / lowest values compared to your other stock groups that you have created.
It is important to note there are two differences between the colour scale on the dashboard compared with the colour scale on the maps.
The areas being compared
Firstly, the colour scale on the maps is comparing all areas across the whole country, whereas the colour scale on the dashboard is only comparing the areas (stock groups) that you have created.
Therefore if a stock group was shaded red for unemployment benefit on the dashboard, this means that there is a high percentage of unemployment benefit in this stock group compared to your other stock groups, but this is not comparing on a national level. Therefore, on a national scale this stock group could actually have a relatively low percentage of unemployment benefit. So if you view this particular stock groups on the map, you may find that the colour scale is different.
The methodology for the colour groupings
The second difference between the colour scale on the map and on the dashboard is the methodology behind the colour groupings.
On the Map: The 5 colour types represent 5 equal sized groups. The colours on the map are based on grouping all areas across England into five 20% bands. So the top 20% of areas on an indicator are shaded dark red, the next 20% shaded light red, and so on
On the Dashboard: The 5 colour types are generated using equal interval classification, defined by the outer range of your areas' data for that indicator. This value- driven method means that we take the highest and lowest value across your stock groups for the indicator in question and then create 5 equal value bands and distribute the stock groups across these value bands. For example, if you had 5 stock groups on the dashboard and the percentage of unemployment in those areas was; 0.1%, 0.1%, 0.2%,0.2% and 1.6%. Then the colour bands would be split into 5 equal groupings based on the values. The five equal groupings would be:
Therefore, in relation to those 5 stock groups mentioned previously, the first 4 with the percentages of 0.1% to 0.2% would be in the lowest colour band and the stock group with the percentage of 1.6% would be in the highest colour band,
This value-driven method on the dashboard was designed to be used to quickly compare your stock groups, allowing you to visually determine the spread of data and relative values.
Key things to remember
- The ranking on the dashboard is based on your stock groups only rather than comparing across England as a whole
- The five colour groups are based on a 5 way equal grouping of the values for the indicators and not like the maps where it is the areas which are grouped in 5 equal groups.
