Free interactive math game: Stem-and-Leaf Plot — Read the table. Part of the Statistics category on MathKite.

Example problems

Taken from the generator that powers this exercise. A fresh set appears every time the page is opened, and the printable worksheet holds ten of them.

  1. What is the largest value in the data set?
  2. How many values are greater than 20?
  3. How many values are in the data set?
  4. How many values are greater than 40?

About this exercise

Reading a stem-and-leaf diagram.

How to solve it

Each leaf combines with its stem to make one value, so a stem of 3 and a leaf of 7 means 37.

Worked example

A stem of 4 with leaves 1, 3 and 8 holds the values 41, 43 and 48.

Common mistake

Reading a leaf as a whole number. Only the stem and leaf together give a value.
