Comparing Data Distributions

Students will compare the distributions of two or more data sets using measures of central tendency, spread, and appropriate graphical representations (e.g., back-to-back stem-and-leaf plots, parallel box plots).

Key Questions

  1. How can we use measures of center and spread to compare two different data sets?
  2. Explain how parallel box plots allow for a visual comparison of data distributions.
  3. Critique the effectiveness of different graphical representations for comparing data.
