Students will launch the Santa Ana statistics investigation by analyzing map-based local data clues, testing quick claims against evidence, and identifying community issues worth investigating through probability and statistics.

Students will refine a focused Santa Ana statistics investigation, test whether their question and hypothesis are investigable, and build a peer-reviewed data and sampling plan that names variables, likely sources, bias risks, and planned graphs before moving into data collection and analysis.

Students will turn their Santa Ana investigation data into defensible statistical evidence, refine claims through critique, and complete a partner-ready infographic and policy brief with explicit limitations, revised visuals, and actionable recommendations.

Students will present their Santa Ana community data story infographic and one-page policy brief to classmates, staff, and invited local leaders, defend how their statistics support their recommendation, and reflect on how data changed their understanding of community issues.
