What are experimental statistics?
Experimental statistics are statistics produced by Statistics Jersey that are in the testing phase and not yet fully developed.
How to interpret experimental statistics
Users should be aware that experimental statistics will potentially have a wider degree of uncertainty. Experimental statistics will be explicitly labelled as such and will contain a clear methodology statement outlining any known limitations and caveats associated with the measures. Details of why the statistics are being published in this form, along with planned further development work will also be included.
Why we publish experimental statistics
The reasons include:
- consultation – experimental statistics are published to involve potential users and stakeholders at an early stage in assessing their quality and suitability
- acclimatisation – where the experimental statistics are alternative versions of existing official statistics, it can help users become familiar with and understand the impact of new methods and approaches
- use – experimental statistics can provide useful information for users as long as their nature is well explained and understood
Labelling experimental statistics
The experimental statistics label is typically used where:
- the statistics remain subject to testing of quality, volatility and ability to meet user needs
- new methods are being tested and are still subject to modification or further evaluation
- there is partial coverage (for example, of subgroups, regions or industries) at that stage of the development
- there may be potential modification following user feedback about their usefulness and credibility
Experimental statistics evaluation
Once the evaluation of the experimental statistics is completed the label may be removed. This decision to remove this label will consider factors such as:
- when it is judged that statistical methods used are robust
- when coverage reaches a good level
- when user feedback indicates that these statistics are useful and credible
- when the defined development phase has ended
