Specification 2a.01 · Paper 1, Paper 2
Revise: Pictorial data representationA stem-and-leaf diagram groups numerical values while keeping every original observation visible. Each value is split into a stem and a leaf.
Order both the stems and leaves in a stem-and-leaf diagram. Include repeated values and an unambiguous key with units.
When reading a stem-and-leaf diagram, reconstruct the whole value: a leaf of 1 on stem 2 may represent 21, not 1.
