Drawing a stem-and-leaf diagram

Drawing a stem-and-leaf diagram.

  • Split each number into a stem and leaf.
  • Order leaves from smallest to largest and retain repeated values.
  • Include a key so the units are unambiguous.

Example 1

Draw an ordered stem-and-leaf diagram, including a key.

The stem gives the tens; the leaf gives the units. Order the leaves and keep repeats.
MedianThere are nine values, so the median is the fifth.
RangeSubtract the smallest value from the largest.
Median 24, range 29.
2 | 4 means 24
