5. COMUNIKOS
An Eurostat research initiative aiming to conduct a review of the current practices in measuring and communicating uncertainty of disseminated data, and to study the latest developments in the field and their applicability to official statistics.
Expected result: enhanced recommendations to tackle the misinterpretation, due to errors or uncertainties, of the information the statistics reveal.

6. What? Challenging Output:
- review and categorise the different sources of uncertainty relevant in the production of official statistics and identify their impact on the disseminated data;
- review the methods and metrics used in official statistics to measure uncertainties, and the methods used in other scientific fields (e.g. physics, meteorology, etc.);
- propose new methods /metrics to present uncertainties based on the review of existing sources and methods;
- case study: uncertainties in scanner data;
- communicate the progress and results of the project
