Section 2: Plotting the Clues

Overarching Themes

This section transitions students from raw data to meaningful visualization through the Analyze Data phase of the Data Cycle. Students move from basic identification of plot types to sophisticated interpretation, learning that different types of data require specific graphical representations to reveal patterns. By engaging in “Plot Walks” and digital analysis in CODAP, students become “Evidence Analysts” who can describe data distributions by their shapes (such as symmetric or skewed). Ultimately, the lessons emphasize that data visualization is not just about drawing graphs, but about purposeful “binning” and profiling to uncover the stories and “profiles” hidden within the evidence.
