Building Scatter Plots and Line Graphs: Sample FAST Questions

Bivariate data in 8th grade gets displayed two ways: a scatter plot when you are looking for an association between two variables, and a line graph when one of the variables is time. Students choose the right display for the context and build it from a data table.

How the FAST tests this benchmark

The FAST uses graphic response items where students plot data points on a grid, plus multiple choice items asking which display fits the situation. Data sets stay at 20 points or fewer, and every point has to land exactly on its coordinates to earn credit.

Skills students need

  • Construct a scatter plot from bivariate data
  • Construct a line graph for data collected over time
  • Choose the appropriate display for a context
  • Read and use the axis scales on a data display
