Published on 09/04/2010

Activity Overview

Students will be introduced to density curves as a simple analysis of a data set. They also will investigate where the median and mean lie on symmetric or skewed graphs.

Key Steps

  • Image

    In this activity, students draw density curves on histograms that have a symmetric, skewed, or uniform distribution. They will compare their sketch to the curve drawn by the Add Normal PDF command on the handheld.

  • Image

    Then students will investigate the relationship of the mean and median of different distributions. After estimating the placement of the mean and median, they will use the Plot Value command see the actual values on the histogram.
