Student Outcomes

  • Students interpret the mean of a data set as a “typical” value.
  • Students compare and contrast two small data sets that have the same mean but different amounts of variability.
  • Students see that a data distribution is not characterized only by its center.  Its spread or variability must be considered as well.
  • Students informally evaluate how precise the mean is as an indicator of the typical value of a distribution, based on the variability exhibited in the data.
  • Students use dot plots to order distributions according to the variability around the mean for each of the data distributions.
