### Median of a Stem-and-leaf Diagram

We already know how to find the Median of discrete data (refer to Mean, Median and Mode)

- Example 1. Below is a stem-and-leaf diagram, with key

3 | 0 1 6 |

4 | 7 7 9 9 |

5 | 5 6 7 8 |

6 | 0 3 3 8 |

7 | 8 9 |

8 | 0 |

Key: 3 | 0 represents 30 |

Find the median |

As there are 18 values, the median (midpoint) is between the 9^{th} and 10^{th} value in the stem-and-leaf diagram.The 9 ^{th} value is 56 and the 10^{th} value is 57. The midpoint between 56 and 57 is 56.5So the median is 56.5 |
