﻿TEACHER NOTES - PHASE 2: EXCEL DATA LAB (45 min)

This is the same Excel lesson students know, now applied to the Phase 1 Boss results.
- Students type their Phase 1 numbers (12 Boss pictures, Round 1; Round 2 accuracy goes in K17).
- Boss files: Excel_Lab_Starter_BOSS_*.xlsx has the 12 picture names ready; Excel_Lab_Example_BOSS_*.xlsx holds REAL Teachable Machine numbers from our own test run (Round 1 = 7/12 = 58%; Nightmare 1/9; Round 2 = 10/12 = 83%; Nightmare 4/9).
- If a student has no Phase 1 numbers, use the Boss example numbers or the original example (Excel_Lab_Example_*.xlsx).
- Formulas and charts: COUNT/SUM/AVERAGE/MIN/IF/INDEX-MATCH/AVERAGEIF, pie, column, line, scatter (XY), bubble (XYZ). Everything is explained in guide-*.html with pictures and a video.

Questions worth asking: Which fruit has the lowest accuracy? (usually Apple and Orange; Banana is robust). Does confidence match correctness? (the scatter plot shows wrong answers with high confidence). How much did Round 2 improve?
