The Brief
What you'll do, and what you'll demonstrate.
Determine which product pairs sell together strongly and reliably enough to justify changing where they sit on the shelf, and prove the expected payoff before committing to a rollout.
This is not a data exercise. It is the work an analyst does when stakeholders need answers from messy data. That distinction matters to every hiring manager who has seen candidates describe statistical methods and none who have extracted insight from messy, real-world data.
When you finish, you will have something most graduates do not: a real-world deliverable, verified by Ewance, that you can show to a hiring manager and say "I did this. Here is the proof."
Earning criteria — what you'll demonstrate
- Tune frequent-itemset mining parameters to the differing purchase frequencies of distinct product categories
- Distinguish genuine, durable association from promotion-driven coincidence using lift and time-stability checks
- Translate statistical patterns into ranked, implementable business recommendations
- Design a statistically defensible retail A/B pilot to validate an expected effect before rollout

Careers
Career paths this challenge builds toward
Completing this challenge demonstrates skills that transfer directly to these roles:
Data Engineer (Retail Analytics)
This challenge mirrors a core retail-analytics task: turning large, messy transaction logs into trustworthy patterns. You practice tuning a mining algorithm to real data characteristics and building a reproducible pipeline that downstream teams can rely on for layout decisions.

- frequent-itemset-mining
- fp-growth
- spark
Decision Scientist
You move from raw association statistics to a defensible business decision, separating real signal from promotional noise and validating expected impact with a pilot. That bridge from analysis to evidence-backed recommendation is the heart of a decision-science role.

- lift-analysis
- ab-testing
- data-storytelling
Experimentation Engineer
Designing a statistically sound store-level A/B pilot, sizing it from a target effect, and guarding against confounds like promotions is exactly what experimentation engineers do to validate merchandising changes before broad rollout.
