Data Storytelling: Turning Numbers Into a Decision

Most data presentations fail before a chart is drawn, because they are organised around what the analyst found rather than what the audience must decide. This cursus starts from the decision, inverts the delivery order, and puts one message in every exhibit. Then charts: why chart choice follows from the comparison, which encodings people read accurately, and how averages hide the finding. It ends in the room, on socialising findings, handling challenge, delivering unwelcome results, and where persuasion becomes manipulation.
