THE RESULT
What the data shows
The largest computed metric is 2.803e+04 for 3.0; the smallest is 2.538e+04 for 1.0. Metric: median (Source monetary units).
Region codes remain as documented source categories; unequal samples are not representative market sizes.
| region | customers | median | p25 | p75 |
|---|---|---|---|---|
| 1 | 77 | 25,385 | 17,184 | 38,699 |
| 2 | 47 | 26,953 | 20,611.50 | 36,158.50 |
| 3 | 316 | 28,029 | 17,209.25 | 42,492.25 |
THE METHOD
From source to answer
Regional sample sizes, medians and quartiles of customer totals.
The Python source exposes this study’s transformations. The complete project download includes shared preparation and evaluation routines.
THE NEXT DECISION
What follows from the finding
Validate regional coverage before interpreting observed mix as market opportunity.
Where the conclusion stops
Annual customer spending uses source monetary units, not an assumed currency. There are no margins, transactions or dates. Customer segments are descriptive and do not establish promotion response.
Related studies may reuse observations or holdouts. These are historical analyses; associations and backtests do not demonstrate commercial impact. Further model tuning needs new, untouched evaluation data.
