Subject
Data Visualization and Reporting
How an analysis reaches a reader, and what the display decides on its way. A chart assigns the reader a perceptual task whose accuracy has been measured, and the scale, the baseline and the aspect ratio each change the comparison performed while leaving every number in place. The subject treats those as analytical decisions rather than presentation, because they are the ones that survive a correct calculation.
Learning paths

Design a display against the question it must answer
- The learner can choose the graphical encoding a stated question requires, justify the choice by what the eye judges accurately, set the scale and baseline so that the visual comparison matches the numerical one, and state which readings the chosen display supports and which it forecloses.
