5.1.6. Stem and Leaf Plot

A character stem and leaf plot of the selected column is drawn. The stem is the number displayed to the left of the vertical bar (|) and each leaf is a digit displayed to the right of it. Each leaf represents a separate data value. Adding the stem value to the leaf digit and multiplying by the leaf unit will give the class to which a data point belongs. For instance:

 

Leaf unit = 1	1|2 represents 12
Leaf unit = 10	1|2 represents 120
Leaf unit = 0.1	1|2 represents 1.2

 

Values are rounded to the nearest leaf unit. The first column in the output represents the number of cases which lie in this row or further away from the median. If the first column has brackets around it, this denotes that the median lies in this row and the number shown is the number of leaves in this row.

Example

Open DEMODATA, select Statistics 1 → Descriptive Statistics → Stem and Leaf Plot and select Output 2 (C9) as [Variable].
