Alan Smith OBE Principal Methodologist ONS Data Visualisation Centre USER needs

WHO ARE OUR KEY USERS? Not all institutes share the same goals: 1.‘show me the numbers’. Everyone does this. 2.‘from data to meaningful information’. Not everyone does this… User needs will be different depending which role(s) a producer is following…

“…Among the Code of Practice requirements are that producers of official statistics should prepare full and frank commentary and analysis that aid interpretation including: information on the quality and reliability of statistics in relation to the range of potential uses information on methods, procedures and classifications factual information about the policy or operational context formats for the presentation of statistics in graphs, tables and maps that enhance clarity, interpretability and consistency… …In the view of the Statistics Authority, the public has a right to know the statisticians’ understanding of the messages from the statistics, just as they have a right to the data itself. It is common, and proper, for statisticians in government departments to brief policy colleagues on the substance of the statistics. That knowledge should, as a matter of principle, be shared more widely.” (The Value of Statistical Commentary, 23 rd July 2010)
