In this activity, students will construct box plots independently and will identify the mean, median, mode, and range of a set of data. Illuminations provides a handout, a link to the box plot tool, and detailed instructions for completing the lesson.

Students will:

  • Compute prices from a menu.
  • Construct and read box plots.
  • Identify the mean, median, mode, and range of a set of data.

NCTM Standards and Expectations:

  • Collect data using observations, surveys, and experiments.
  • Represent data using tables and graphs such as line plots, bar graphs, and line graphs.
  • Describe the shape and important features of a set of data and compare related data sets, with an emphasis on how the data are distributed.
  • Use measures of center, focusing on the median, and understand what each does and does not indicate about the data set.
