Snack Strategy Project GuideMISSION: SNACK STRATEGY Unit 3: Data Analysis Review Mini-Project CASE STATUS: ACTIVE Case Brief The school vending machine company is failing. Their snacks are ignored, and they don't know why. Your mission, Data Detective, is to collect classroom data, manipulate it for insights, visualize the findings, and provide an ethical recommendation for the ultimate snack selection. Collection (3.01) Design a survey to collect snack preferences and plan secure storage. Manipulation (3.02) Clean, sort, and calculate totals to find patterns in your evidence. Visualization (3.03) Transform raw numbers into a clear visual chart for the stakeholders. Ethics (3.04) Ensure privacy, obtain consent, and identify potential bias. Operational Phases 1 Phase 1: Surveillance & Collection Survey 10 people in the room. Record their favorite snack, snack frequency, and one dietary restriction. Determine how you will store this data safely. 2 Phase 2: Evidence Processing Clean your data (remove errors), sort it by preference, and calculate the "Most Wanted" snack based on frequency and popularity. 3 Phase 3: Visual Reporting Create a bar chart or pie chart summarizing the top snacks. It must be clear, labeled, and professional. 4 Phase 4: Ethical Review Analyze your survey for bias. Did you ask only your friends? Is the data anonymous? Write an ethical disclaimer.

(e.g., if you only asked people in one grade level, would the results work for the whole school?)

Calculation Total up the votes for each snack category. "Raw data is evidence; cleaned data is a story." Phase 3: Visualization (3.03) The vending machine owners don't have time to look at lists. They need a Picture of the data. Chart Essentials: Descriptive Title X-Axis Label Y-Axis Label Clear Scale PHASE 4 Ethical Integrity (3.04) Bias Check Did you only ask your friends? If you only interview 3rd graders, can you really recommend snacks for the whole school? Privacy Keep subject identities secret. No names should appear on your final report! Integrity First.
