  • Test Item Specifications
    • Reporting Category: Data Analysis
      Item Type(s):
      This benchmark will be assessed using: MC items.
      At Grade 8, this benchmark will be assessed using MC items.
      Clarification: Students will interpret data displayed in box-and-whisker plots, scatter plots, and line graphs and make conjectures.

      Students will construct box-and-whisker plots, scatter plots, and line graphs to display a given set of data.

      Students will explain how different displays of data lead to different interpretations of the data.
      Content Limits: Data sets used in items should be limited to a maximum of 12 data points and three categories.

      Students will make conjectures/interpret line graphs, pictographs, single/multiple-bar graphs, circle graphs, stem-and-leaf plots/tables, histograms, and appropriate data displays, including box-and-whisker plots, scatter plots, and lines of best fit.

      Items should have no more than two box-and-whisker plots from which to interpret data.
      Stimulus Attributes: Items may ask students to use statistics to interpret and analyze real-world situations.

      All items should be set in a real-world context.

      Graphics should be used in all of these items.
      Prior Knowledge: Items may require the student to apply mathematical knowledge described in the Standards from lower grades. This benchmark requires prerequisite knowledge from MA.3.S.7.1, MA.5.S.7.1, and MA.7.S.7.2.
