Accuracy and reliability

Overall accuracy

The statistics are based on official, industry-recognized readership measurements of Index Denmark/Gallup. Referring to the original sources for a review of the statistical processing.

Sampling error

Not compiled for this statistic. Referring to the original sources for a review of the statistical processing.

Non-sampling error

In addition to the statistical uncertainty in the measurement of readership figures in the original sources, typing, coding and calculation errors in the data processing can be sources of uncertainty.

Quality management

Statistics Denmark follows the recommendations on the organisation and management of quality set out in the Code of Practice for European Statistics and the accompanying implementation model, the Quality Assurance Framework. Read more about these on the page Quality in official statistics.

Quality management is supported by common principles, guidelines and managerial responsibility for quality in statistical products and processes. The aim is to ensure a systematic and consistent approach to quality across the entire statistical production.

Quality assurance

Quality assurance at Statistics Denmark is integrated into the statistical production processes and is carried out in accordance with the principles of the Code of Practice for European Statistics. Read more on the page Quality in official statistics.

Quality assurance includes the continuous use of standardised procedures, documentation in line with international standards and internal controls related to data collection, data processing and dissemination. Experience gained from production is continuously used to identify needs for adjustments and improvements.

Quality assessment

No actual quality measurement has been carried out, but the statistics are considered to be relevant for users with an interest in the development of the population's media consumption. It is not possible to identify and quantify the various sources of uncertainty in the available material, but as the statistics are based on the official, industry-recognized measurements of readership figures from Index Denmark/Gallup, accuracy and reliability are considered to be satisfactory. With the annual update of statistical bank tables, the timeliness and availability of statistics is probably satisfactory for the generally interested user, but probably satisfactory for a professional in the media industry, who is therefore referred to other publications of Index Danmark/Gallup's results. It is possible to follow the development within newspapers over time by comparing several StatBank tables, but there are data breaks in relation to methods etc.

Data revision - policy

Statistics Denmark revises published figures in accordance with the Revision Policy for Statistics Denmark. The common procedures and principles of the Revision Policy are for some statistics supplemented by a specific revision practice.

Data revision practice

Only final statistics is published.
