Create a Box Plot of My Data

Find your work about a typical sixth grade student from the lesson "Describe a Sixth Grade Student". Copy your line plot from Lesson 7, Task 3, into your notebook.

  • Find the five-number summary for your data.
  • Draw the box plot directly above your line plot.
  • On your box plot, label the lower and upper extremes, the lower and upper quartiles, the median, and the interquartile range (also called IQR).

Hint:

Follow these steps to draw a box plot:

  • Calculate the numbers in the five-number summary.
  • Draw a box from the lower quartile to the upper quartile (this is the interquartile range, or IQR).
  • Draw a line segment from the left side of the box to the lower extreme of the range, and a line segment from the right side of the box to the upper extreme of the range.
