What’s right and wrong with them, how to improve them, do we need them, can we replace this one or that one with administrative data, why do the media (and nearly everyone else) so misunderstand and misinterpret them… those...

A conundrum for Microsoft Power BI I’ve been familiarising myself with Microsoft Power BI, which features prominently in any current discussion on data analysis and dissemination tools for organisations.
