The Motion Chart can be used to visualize how district performance changes over time. The chart displays district information in three formats: as circles plotted on axes, as a bar chart, or as a line chart. The menus for the Y and X axes can be used to show results for all students, students eligible for the National School Lunch Program, or by students' race/ethnicity. The color coding of the chart and the size of the bubbles can also be associated with any of these student groups.
Because NAEP is using the Google Motion Chart to create this data visualization, interpolated data appear for years when assessments were not administered. For instance, there was no reading assessment in 2004, but the graphic visualization inserts the rounded average of the 2003 and 2005 estimates for 2004. Results shown for 2004, 2006, and 2008 do not represent actual NAEP average scores.
All apparent differences shown in this chart would need to be tested for statistical significance before drawing conclusions. Visit the NAEP Data Explorer to view complete data for all students, and by race/ethnicity and family income. For more help, read about how to use the Motion Chart (295K PDF).
