  8. CapstoneRetail performance review: two years of Lumen Bay StoresAudit two years of store-week data, build the KPIs a board actually needs, compare store formats at the right unit of analysis, separate holidays from trend, estimate the promotion effect three ways with honest uncertainty, and write the executive recommendation.
  9. CapstoneFull statistical investigation: from a messy export to a decisionTake a raw customer export full of duplicates, typos, placeholders, impossible values and a unit mix-up; audit it, clean it with documented rules, analyse the cleaned data, and show which conclusions survive — and which collapse — when the cleaning changes.
