Problem

货拉拉小面/大面客单价提升,而整体客单价下降

Asked in the round 1 stage. Small-van and large-van average order value both increased but overall AOV decreased; explain.

  1. Define overall and segment-level average order value precisely.
  2. Decompose the movement and explain the likely statistical cause.
  3. Specify the data needed to validate the explanation.
  4. Recommend follow-up analyses and business actions.

Data available: Order-level records containing order amount, vehicle type, order time, city, route distance, service type, status, and discount information.
