📝 Data Plan and Graph Draft

Teams build a one-page investigation plan that includes survey questions, sampling method, anonymity steps, variable definitions, and a draft procedure for making a scatter plot and a two-way frequency table with relative frequencies. They sketch axis labels and scales for screen time vs. math grade, set category thresholds for the table, and outline how they will check for missing or unusual data. Midway through, teams give feedback to 2 peers, receive feedback, and revise their plan before submitting the final version as a milestone gate for moving into data analysis.
