Know:

  • How to use data to create a box and whisker plot

Understand:

  • that a box and whisker plot can help us to visually represent data

Do:

  • I can construct a box and whisker plot..

Box and Whisker Plots

Box and Whisker plots are an easy way of organizing data. It shows our min/max values as well as median of our data.


 

Creating Box and Whisker Plots

  1. Organize your data in ascending order (smallest to biggest)
  2. Find the min/max values
  3. Find the median of the data
  4. Find the median value of Quarter 1
  5. Find the median value of Quarter 3
  6. Draw your lines with min/max values
  7. Add in Q1 and Q3 values and draw box around the two values
  8. Add in your median value and draw a line to split the box.
