Use descriptive stats like range, median, mode, mean and outliers/gaps to describe the data set.
Clarifications:

Essential Understandings

Concrete:

  • Given a scatter plot, identify outliers in the data set.
  • Identify the highest and lowest value in a data set given a number line and matching symbols (concept of range).
  • Identify the representation (use plastic snap cubes to represent the tally showing the number of occurrences) of the concept of mode.
  • Identify the concept of median using concrete representations of data (create a bar graph with an odd number of bars using snap cubes; arrange from shortest to tallest; student place fingers on two outside towers, knock towers over and move inward until they reach the one middle tower left standing).
  • Find the mean using concrete materials.
Representation:
  • Identify the mode and the spread of the data using a line drawing of the distribution.
  • Calculate the mean using pre-slugged template of data points.
  • Order data set using numeric symbols.
  • Understand the following concepts and vocabulary: median, mode, mean and outliers.

Cluster: Summarize, represent, and interpret data on a single count or measurement variable. (Algebra 1 - Additional Cluster) (Algebra 2 - Additional Cluster) : 

Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.
