Today s lesson

Today’s Lesson

  • Today we will learn about a new type of graph.

  • It is called a whisker box


Eq what are whisker boxes

EQ: What are whisker Boxes?


Take some notes

TAKE Some Notes

  • Box and whisker plots

  • A box and whisker plot is used to display information about the range, the median and the quartiles. It is usually drawn alongside a number line


Whisker box is a type of graph

Whisker Box is a type of graph

FIVE POINT SUMMARY More detailed than reporting only median, but less detailed than showing a histogram or stem & leaf diagram, is the FIVE NUMBER SUMMARY


Example 1

Example #1:

  • Example

  • The oldest person in Mathsminster is 90. The youngest person is 15.

  • The median age of the residents is 44, the lower quartile is 25, and the upper quartile is 67.

  • Represent this information with a box-and-whisker plot.

  • Solution

Class activity

Class Activity

  • You have three post-its

  • Write your name on each

  • Use one to records your

  • Height

  • Age in Months

  • Shoe Size


Human whisker box plot

Human Whisker Box Plot!

  • Now that we have our data we are going to create a human whisker box.

  • Lets use our height data first!

  • Line up in order from least to greatest.

  • Lets find the Median

  • Now separate the Upper and Lower halves of the data

  • Let’s find the middle of the lower half.

    • This is the lower quartile

  • Now we will find the middle of the upper half.

    • This is the upper quartile

  • 6. Time to identify the upper and lower extremes.


  • Let s try one more time

    Let’s Try one more time

    • Now that we have our data we are going to create a human whisker box.

    • Lets use our ages in month next !

    • Line up in order from least to greatest.

    • Lets find the Median

    • Now separate the Upper and Lower halves of the data

    • Let’s find the middle of the lower half.

      • This is the lower quartile

  • Now we will find the middle of the upper half.

    • This is the upper quartile

  • 6. Time to identify the upper and lower extremes.
